摘要
以祁连山区肃南县为例,分析了祁连山区山地草原荒漠化的现状及其危害,并结合历史,从自然和人为两方面探讨了草原荒漠化的成因。由于自然因素是形成草原荒漠化的基础,而人为因素才是其主导因素。所以本文主要就人为因素有针对性地提出了山地草原荒漠化的防治和生态环境重建的对策,即加大资金投入,引进和推广新技术;减轻草原人畜压力;实现合理用水,提高草原的数量和质量。
Taking Sunan County in Qilian mountain area as an example mountain-grassland desertification,the paper analyzes the eauses the present state and the imperilment of in Qilian mountain area,and combining its history,from the perspective of nature and humans probes into reasons of grassland desertification.The natural factors are the basis of forming grassland desertification,and human factors are its dominance. So the paper puts forward a series of control for grassland desertification and reconstruction countermeasures for ecological environment mainly in human factors.These measures include increasing capital input and introducing and popularizing some new techniques, reducing grassland pressure on population and livestock,and realizing reasonable use of water to improve grassland quantity and quality.Implementing these measures can inhibit more development of grassland desertification,and result in the healthy development of regional environment.
