The Black Land Protection Law of the People's Republic of China will be officially implemented from August 1st

The "Black Land Protection Law of the People's Republic of China" will be officially implemented from August 1 this year, which is the first time that my country has legislated to the protection of black land. In order to comprehensively and systematically grasp the information such as the distribution, structure, quality, and use status of my country's black land, the country launched the Northeast Black Land surface matrix survey for the first time in the first half of this year. At present, the survey area has been completed by 83,400 square kilometers.

The surface matrix is ​​the basic substances of various natural resources such as forests, grasslands, water, and wetlands such as forests, grasslands, and wetlands. Affected by geological effects, natural effects, and human activities, the surface matrix of different depth levels has different production and ecological service functions.

The reporter learned that the survey area of ​​15 black land surface matrix survey has been completed in the survey area of ​​83,400 square kilometers, and the length of various types of drilling reaches 12,228 meters. 8,885 survey points have been completed, 33021 are collected and analyzed. The distribution characteristics of black earth resources, the thickness of the surface of the surface of the surface, and the thickness of the soil layer.

The Ministry of Natural Resources said that the underground survey of the black land surface is based on the third national land survey results as the bottom map, and it is supported by modern technology methods such as high -scoring remote sensing and integrated surveys. The means of "quantity, quality, ecology" survey of black land surface matrix "quantity, quality, ecology".

Hou Hongxing, Chief Expert of Black Land surface matrix survey project: From the surface to the ground, from macro to micro, there are observation sampling here in macro, to micro, there are identification analysis and testing, and so on. On this basis, we will conduct an overall investigation of the spatial structure model of the geological layer of the black land on the surface of the black land from point to the line.
