Since the 1980s China has made great efforts to conduct the construction of ecological agriculture and has tried every means to find a sustainable agricultural development mode that can not only increase the output of grain and other farm produce, but also help improve the ecological environment.

八十年代以来，中国积极进行生态农业建设，寻求既能增产粮食等农产品，又能使生态环境得到改善的农业可持续发展模式：综合治理小流域水土流失面积6700多万公顷；建立了不同类型、县乡村不同规模的生态农业试点2000多个

Restoration Ecology was ranked as one of three hotpots in biological field as well as biological diversity and global climate change in recent years, which is one fresh branch of Modern Ecology.The causes of degraded ecosystem, techniques and methods of degradation in ecosystem restoration and reconstruction, process and mechanism of ecology whose objectives are the destroyed ecosystems under the stress of natural catastrophes and human activities were primarily researched in the paper.

恢复生态学与生物多样性和全球气候变化并列为生物领域的三大研究热点，它主要研究生态系统退化的原因、退化生态系统恢复和重建的技术与方法、生态学过程与机理的科学，是现代生态学的年轻分支之一，其研究对象是一些在自然灾变和人类活动压力下受到破坏的生态系统。

With frangible environment and lack of land, water and forest in karsts lava region, it encounters technologic challenges to ecological rehabilitation of opencast mine region by traditional methods.
