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 alpinecold 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.
