甘南黄河重要水源补给区生态经济功能区区划研究

以甘南黄河重要水源补给区(以下简称甘南黄河源区)TM遥感影像数据及统计年鉴数据为依据,选用植被覆盖度、水源涵养重要性、土地利用格局、人口密度、农产品提供、动物产品提供等生态因子,用层次分析法(AHP)获得各因子权重,进行分析计算,将甘南黄河源区划分为城镇建设与生态农业经济区、沿黄河水源生态补给区、沿洮河农林生态经济区、畜牧业产品提供与生态旅游区、玛曲畜牧业产品提供区。通过对区域内在联系的分析,阐明不同区域的生态特征和生态经济发展中存在的问题,探讨区域的发展方向、途径和对策,从而为甘南黄河重要水源补给区生态?经济?社会的协调发展提供依据,对甘南黄河源区区域保护、建设和开发具有一定的指导意义。

Research on eco-economic functional regionalization of important water supply region of the Yellow River in Gannan area

Using TM image and statistical yearbook data of the Yellow River source in Gannan area, Gansu Province, along with vegetation coverage, water conservation, land use pattern, population density and agricultural and animal products as ecological factors, the eco-economic functional regionalization of important water supply region of the Yellow River in Gannan was conducted. An analytical hierarchy process was developed to weigh ecological factors in study area. Based on the weights of the ecological factors, the Yellow River source region in Gannan was classified into town construction and eco-agricultural economy zone, hydro-ecological recharge zone of the Yellow River, eco-agricultural economy zone of the Tao River, livestock product supply and ecological tourism zone, and livestock product supply zone of Maqu. The ecological characteristics and problems in eco-economic development of different zones were discussed through analysis on the internal connection among different zones. The developmental directions, ways and countermeasures were also advanced. The findings of the research could provide guidelines for protecting, constructing and developing the study area.
