Causes and countermeasures of degradation and desertification of natural meadow in Haibei District of Qinghai Province
摘要
Abstract
The natural meadow resources were abundant in Haibei district, but the desertification and degeneration became serious gradually with the continuous stockbreeding development for many years. According to the fact of natural meadow deterioration and desertification in Haibei district, this paper analyzed the harm of meadow deterioration and desertification, expatiated emphatically the multi-layers causes, and put forward corresponding countermeasure and suggestions. The result showed that the direct causes of meadow deterioration and desertification in Haibei were overloading, overgrazing and the break of biological chain; the indirect causes were population increment and livestock technical application, the fundamental causes were frangibility of meadow ecosystem environment induced by alpine-cold climate characteristic and complicated geography. Finally, three strategies were put forward, including encouraging family planning, increasing education investment, controlling and reducing the husbandry population, implementing modern and efficient stockbreeding development mode, developing artificial grassland, determining domestic animal number according to forge production, building the protection consciousness, and developing finite governance of natural meadow.关键词
