Progress on evaluation of Alpine grassland degradation degree in Qinghai Province

Abstract

The alpine grassland in Qinghai Province is very prone to degradation, and the local ecosystem is fragile. If damaged, it is difficult to recover in a short time. Because of alpine grassland degradation phenomenon will directly threaten the local ecological security and economic development, so the current research scholars strengthen the assessment of the degree of degraded alpine meadow, pay attention to the alpine grassland degradation phenomenon from the perspective of practice to master the spatial distribution law of deep excavation latent information value, in order to provide evidence for effective protection measures. On the basis of understanding the current alpine grassland degradation phenomenon in Qinghai Province, this paper systematically collected local basic geographic, social economic, scientific investigation and other data information, combined with the basic law of alpine grassland degradation, and used geographic information technology and statistical methods to determine the evaluation results of alpine grassland degradation degree in Qinghai Province. The final results showed that although the degradation of the local alpine grassland was still severe, with the improvement of the attention of various departments, the grassland protection work had achieved excellent results.
