Abstract

The environmental health and green development of the water source area of Mid-Route of the South-North Water Diversion Project (SNWDP) is not only essential for ensuring that “The clear water is sent to Beijing”, but also an important prerequisite for sustainable development of society and economy in the water source area. Based on national geographic survey data, basic surveying and mapping data and statistical yearbook data, this paper used the model of relative carrying capacity of resources to estimate and analyze the carrying capacity of relative natural resources (CCRNR), carrying capacity of relative economic resources (CCRER) and carrying capacity of relative resources (CCRR) and their spatial-temporal changes in the Danjiangkou Reservoir area of the water source area of the Mid-Route of SNWDP from 2009 to 2015 by Geographic Information System (GIS) technologies. The results were shown that: (1) CCRR increased significantly compared with that in 2009. However, CCRR in the study area was still overloaded in 2015. (2) CCRNR was rich, but decreased from 2009 to 2015. (3) CCRER was in a overloading state, which increased obviously from 2009 to 2015. The improvement of CCRER was the main reason for the sustainable growth of carrying capacity in the study area. Therefore, the countermeasures including making rational use of natural resources, developing economic resources and controlling population quantity were proposed to promote the sustainable development of society, economy and ecology in the study area.
