Kaihua County builds the "Communist Forestry" application to help Xinglin Farming

Text/Xia Shengmin, Secretary of the CPC Kaihua County Party Committee

Kaihua is located in the source of the west of Zhejiang Province and the Qiantang River. As a forestry county, the concept of digitalization penetrates the entire process of protection, utilization and development of forestry resources, and take the lead in creating the application of Forestry in the country throughout the country. The three major scenes of the economic wisdom of the forest "and the" forest carbon existence "are initially achieved" one -click treatment "of forest disasters," one -click control "of the forest economy, and" one -click analysis "of forestry carbon exchange. The application is included in the major application of Digital Reform in Zhejiang Province "One Account S1". On March 6th, Zhejiang Political Nail was launched. As of June 20, the discovery rate of pine material nematodes increased from 40%of the traditional census to 90%, and 25 subjects were settled through the economic intelligent site of the underwriter. The planting area reached 24,000 mu. , Carry out the first "Zero Carbon Asian Games" carbon exchange development in Zhejiang Province.

1. Reform needs

Kaihua County is the only national park system pilot county in the Yangtze River Delta. It has a total of 2.87 million mu of forest land in the county. It is of great significance to do a good job in the protection of resource protection, promote the transformation of forest resources, and realize the overall wisdom of forestry. However, there are still several problems in the protection, utilization, and development of forestry resources: First, the protection of forest resources is difficult, and the effectiveness of disaster prevention and control is not obvious. Forest fires and pine material width disease prevention and control situation is severe. In 2021, the pinematic thread width disease in Kaihua County reached 15,000 acres, accounting for 5%of the pine forest area in the county. It is mainly based on labor, low discovery, low response disposal, poor linkage mechanism, and not high degree of accuracy and closed -loopization. The second is that the economic development under the forest is difficult, and the effectiveness of farming to increase income is not obvious. The situation of Kaihua Mountains is complicated, and it is difficult to fully grasp the situation of the forest conditions, the composition of the forest, and the traffic conditions. The base management level of the main body is not high, the product traceability is not accurate, the market is not smooth, and it is difficult to be large -scale and systematic, and it is not obvious that the increase in the surrounding forest farmers' income is not obvious. The county's forest carbon exchange resources are unclear, and forest -solid carbon exchange measures are not accurate; the cost of manual monitoring of carbon exchange is high, and the project development process is complicated.

Second, scene construction

Comprehensively use advanced data collection equipment such as drones, laser radar, and high spectrum, and share the use of digital management platform resources such as forestry space and geographical information in Zhejiang Province, and units such as emergency management, agricultural and rural departments, Qianjiangyuan National Park Administration Bureau and other units Cooperate and co -construction, open up 8 sets of cross -departments and cross -level systems, collect more than 700,000 forest ecological resources data, and create a digital twin base for forestry resources.

1. "Forest Disaster Prevention and Disaster" scene. Using technologies such as all -weather monitoring, drone regular cruise and laser radar positioning of high -altitude gimbal, quickly complete the collection, analysis, and positioning of disaster data in the forest area. Once insect diseases and fires occur, the system will be displayed in real time and automatic warning. At the same time, Unicom emergency management, forest management and protection systems will be sent to regional managers, forest guards and disposal personnel. Find the disaster point, and carry out on -site verification, disposal, report to achieve fast response and quick disposal. After the disposal is completed, after the on -site personnel report the processing process and results through the system, the system automatically adopts the drone for re -flight verification to achieve the full sales number and full closed loop, which effectively avoids the further spread of forest disasters. By combining the distribution and diffusion of pine materials in various towns and towns in Kaihua County for nearly 3 years, the deduction model of changes in the epidemic disease in pine materials is established, the hierarchical prevention and control areas are provided, and the best solution for preventing and disposal is provided.

2. "Under the Forest Economic Intelligence" scene. Focusing on the intelligent site selection of economic development under the forest, the intelligent needs of the main body management, through digital twin technology, the twin simulation of real scenes is carried out to provide a reference for decision -making for project management. The "smart location" module adopts "drone+remote sensing" to collect information, water sources, landforms, forests and other information, combined with artificial investigation of factors, soil, vegetation, ownership and other factors, through data gathering analysis, and building forests to build forests. The "one picture" of the planting area is suitable for the planting area. When carrying out project recruitment, the operating entity can import data such as the cultivation conditions and technical standards of Chinese medicinal materials according to its own needs. Essence "Project Management" module, through the development of the base three -dimensional modeling, integrated base video surveillance, meteorological monitor, soil sensor and other facilities collected data, the business entity can be visible in real time on the management platform to achieve full supervision; by reporting the product quality inspection report, reporting the quality of Business management records import traceability system, consumer scanning traceability source code, can check the full life cycle of product production, and realize the whole process traceability.

3. "Forest Fixed Carbon Increase" scene. Focus on the "double carbon" and common wealth work goals, and use forest carbon exchange value mining to promote forestry efficiency and forest farmers' income. The "Carbon Storage and Carbon Exchange" module uses carbon exchange forestry project method and forest -operated carbon exchange project method to complete the county's carbon storage amount of carbon storage. At present, the county's forest vegetation carbon reserve is 6.4 million tons, the forest vegetation year carbon exchange exchange The amount is 670,000 tons. The "Carbon Account" module, through the carbon account system, each operating entity can automatically measure its own carbon reserves and carbon exchange volume, independently participate in the development of carbon exchange projects, and carry out carbon exchange transactions in the province. The "Carbon Monitoring" module cooperates with Zhejiang Agricultural and Forestry University to change the original manual monitoring method with a large amount of workload and cumbersome procedures, innovate the digital monitoring mode of forest carbon exchange, and measure the height of the tree with the drone laser radar and the calculation of the chest diameter. The accumulation of accumulation, calculating the forest carbon exchange capacity, and through multiple calculations and algorithm corrections, gradually realize unmanned carbon exchange monitoring instead of traditional manual monitoring, cracking high costs in carbon exchange transactions and difficulty monitoring. The "Carbon Engineering" module cooperates with the Zhejiang Forest Resources Monitoring Center to adopt CCER methodology (the calculation method of voluntary emission reduction of greenhouse gas proof). Regional carbon remittances, establish forest carbon exchange forecast models, carry out carbon exchange time and space, potential analysis, and predict the growth of carbon exchange in different business types in key forestry projects such as national reserve forests and central land greening demonstration projects, assisting providing forest growth Optimization of accurate measures for operations. Third, breakthroughs in reform

The first is to reconstruct the closed -loop process of forest diseases and insect pests, and the disaster prevention and control accelerate cost reduction. The use of digital twin technology to achieve forest disaster discovery and disposal of one -button order, real -time supervision, establish a digital management system for pine material nematode disease, and build a full process of "scientific early warning, precise discovery, fixed -point treatment, efficient inspection, and full -process control". Pine material thread diseases are concentrated in the treatment period, and the county's epidemic cleansing time is shortened by 1 month compared with previous years, from staged division to normalization, and basically realized dynamic clearing; The overall prevention and control of manpower and capital costs decreased by 25%and 50%, respectively to protect the ecological resources of the forest and keep the bottom line of ecological protection.

The second is the economic intelligent management model under the innovation forest, and the industrial development is accurate and fine. The project owner develops a "one picture" through the Chinese medicinal materials under the forest to achieve intelligent location. For example, Luzhou Yuanyi Ecological Agricultural Technology Co., Ltd. successfully landed in Jiangjia Village, Linshan Township, Kaihua County through the application system, and developed the white pupae and Huang Jing of more than 10,000 acres of Lin. Essence Through the enterprise "providing seedlings, technical guidance, and prostitution acquisition", village collectives and forest farmers "provide labor, rent forest land, and autonomous planting", create a new model of "leading enterprise+village collective+farmers" Management and Qianjiangyuan regional public brand empowerment, enhance product value and competitiveness, and initially realize the win -win situation of the government, business entities, and village collectives (forest farmers). 110, more than 4,500 beneficiary farmers.

The third is to optimize the development process of forest carbon exchange, and the transformation of carbon exchange is convenient and efficient. Establish a digital metering monitoring system for forest carbon exchange, the monitoring time of the "zero carbon" Asian Games 25,000 mu carbon exchange project development has been shortened from 15 days to 3 days; optimizing the carbon account system of Zhejiang forestry, 29 documents developed by carbon exchange projects Optimized integration to 9 items, the optimization rate reached 68.9%, and achieved cost reduction, difficulty reduction, and efficiency of carbon exchange development. Through the analysis of forest carbon exchange prediction models, it assists providing forest exchange operation measures to promote accuracy of carbon exchange growth, realize an annual increase of 1.35 million tons of carbon exchange, 50 yuan/ton of carbon exchange price, 20 -year meter, and open after 5 years later The county is expected to earn 1.35 billion yuan (2.7 million mu*0.5 tons/year, acres*20 years*50 yuan/ton), covering 30,000 farmers in the county, achieving an average income of 45,000 yuan. Innovative green finance supports the forest carbon exchange mechanism, the first "zero carbon companion" carbon exchange pledge loan ("forest carbon exchange value+forest right/public welfare forest income right" portfolio loan) in Zhejiang Province, a total of 13.84 million yuan in loans.
