- Abstract:
-
Population carrying capacity is an important factor of regional sustainable development. Yanchi, Hongsibu, Tongxin and Haiyuan County in central Ningxia were selected as research area.We used the ecological footprint model of sub-national hectare to measure population carrying capacity of the various counties (districts) in the study area. Result shows that Yanchi County in the ecological surplus state, has the population of 41 000 ecological carrying space. Hongsibu area, Tongxin and Haiyuan County are in different degrees of ecological overload condition. Haiyuan County has the worst ecological overload, overload population is 51 000, overload population of Tongxin County is about 38 400, Hongsibu area is the minimum ecological overload, overload population is only 21 200. From the point of ecological population carrying capacity, if the population is unchanged in the area, the factors that influence the regional ecological population capacity are the per capita consumption level and production capacity of cultivated land, under the current level of science and technology, the production capacity of cultivated land is mainly restricted by water resources. Therefore, under the condition of limited water resources, improving production technology and reducing population of the area can alleviate the pressure of the ecology of the region.
