【Abstract】 Hilly land regions are the seriously damaged ecosystem in China,the ecological protection and restoration of mountain-river-forest-farmland-lake-grass system in hilly land( referred as meta-ecosystem) is urgently needed,which is extremely important for the construction of national ecological security barrier. Taking Jiawang district of Jiangsu province as an example,this paper identified the important protection and restoration areas,presented the general idea of protection and restoration of meta-ecosystem in hilly land,established the overall pattern of protection and restoration,clarified the key direction of ecological protection and restoration. The construction of ecological protection and restoration mode is adapted to the new requirements of high quality development,which can effectively improve the quality and service function of ecosystem,and provide reference for the protection and restoration of metaecosystem in similar areas.更多还原
