How to save a grassland?

China News Network, Changchun, June 18th (Reporter Guo Jia) "Tian Cang Cang, the wild. However, nowadays, the grassland you can see may be "Asakusa to have no horseshoe."

In recent years, in Gan'an County, Jilin Province, the hinterland of Songnen Plain, the World Nature Foundation has carried out the "pilot of grassland recovery and sustainable management" with relevant local government departments, making a grassland with severe degradation and saline -alkaliized grassland.

June 18th is the sixth "Prairie Protection Day" in China. Ge Yan, a specialist project commissioner of the Changchun District Resident Working Group of the World Nature Foundation, accepted an exclusive interview with a reporter from China News Network, telling the story of their restoration of the grassland.

Qian'an County is located in the hinterland of Songnen Plain. It is one of the semi -agricultural and semi -animal husbandry counties in China. The grassland has shown degeneration, saline and desertification trends. In 2019, in order to understand the reasons behind the World Natural Foundation project, they visited the farmers and herdsmen in the surrounding communities and the managers of the local grassland workstation in Qian'an County. Through a lot s solution.

Ge Yan introduced that the project team chose a grassland with an area of ​​about 11 hectares and a typical significance of salinized. According to the grassland vegetation and soil conditions, they divide the grass field in four areas, and different regions use different recovery methods.

The first step to restore the grass field is grass. Ge Yan introduced that, like farmers planting land, they first rake the land and retain the sheep grass communities with good growth. Four local grass species.

The project team set up 10 infrared cameras at the pilot grassland to continuously track the growth of vegetation. Around the pasture, they set up temporary fences to prevent livestock and poultry from entering. "Restoring the grassland is not just as simple as planting grass. An important criterion is that the benign alternative of the vegetation community structure and tend to stabilize, and the biological diversity in the system is effectively recovered." Ge Yan said.

One year later, the World Nature Foundation and researchers of the Institute of Nature and Ecological Research Institute of Heilongjiang Provincial Academy of Sciences conducted a biological diversity investigation of the grassland. The results of the survey showed that the grassland vegetation in each area not only had good growth, but also the figures of many animals, and the rodent capture rate increased by 0.5%.

After the pilot achieved initial results, the project team continued to explore a local grassland management and business model for sustainable development. Ge Yan said that the restoration of the grassland should not be limited to the restoration of ecological indicators such as grassland vegetation and biological diversity, and to develop sustainable grassland utilization and management models for local community residents.

However, how to coordinate the actual problems of protection and development is still a big problem. In this regard, Hui Zhiyuan, a researcher at the Institute of Nature and Ecology of Heilongjiang Provincial Academy of Sciences, said that in the management countermeasures of grassland management, on the basis of following the principle of non -degradation of the grassland, a moderate grazing and cutting management system can be used. The analysis of the response of climate change and the changes in economic profits, determine the best grazing rate of regional grassland, weigh risks and profits, and promote the coordinated development of ecological environment and economic environment in pastoral areas.

Li Zhiyuan said that the grassland ecological recovery is a systematic project. At present, common measures for grassland ecological restoration include fences, replenishment, fertilization, mechanical pine soil, and artificial grassland. New technologies and new materials, comprehensive research results, continuous innovation, forming a diversified and integrated technical system, making the degraded grassland ecological restoration and governance tend to refine management.

In the pilot pilot, the project team found an active red fox family, and Ge Yan named one of them "Huanhuan". "" Huan, joy and joy "in" Speaking of the Words ", we expect to use slim grass to redefine ecological barriers to reproduce the beautiful pictures of the grass -long warbler flying shepherds." Ge Yan said. (Finish)
