| 摘 要： | 提出甘肃省草地资源退化状况,分析得出人为破坏、草地超负荷利用、草地鼠虫害频繁发生、草地群落物种数减少、草地生态系统生产力下降、不合理的开矿、草地保护、管理意识不强等因素导致了甘肃省草地资源的日益退化。最后指出要恢复草地生态系统,必须从以下七个途径入手,既①强化宣传教育,依法管护草地资源;②科学规划,分类指导;③规模种植,加快人工草地建设;④加强围栏封育;⑤大力实施草地改良;⑥依靠科技进步,保护和建设草地资源;⑦从空中要水。这将对甘肃省乃至西北地区草地生态系统的恢复与重建提供一定的参考。

| Abstract: | In this paper, the degradation condition of grassland resources in Gansu province, China, was put forward. The causes for degradation of grassland resources were analyzed, including artificial destroy, heaven burden, numerous mice and insect pests, decrease of species in grassland community, decline of productivity of grassland ecosystem, absurd mine exploitation and poor management. Measures for protection, management and recovering of grassland resources were pointed out in Gansu province, including education and laws, scientifically programming and guiding, building artificial grasslands, limiting browsing, improving grasslands effectively, protecting grassland resources according to the progress of science and technology, and artificial rainfall. This will be helpful to recovering and rebuilding of grassland ecosystem in Gansu province and Northwest China. |
