Spatial Variation and Relevant Influence Factors of Green Development Levels Among the Counties in Ningxia
基于2013年数据，采用熵权法、改进TOPSIS和障碍度模型，研究了宁夏各县域绿色发展水平的空间差异及限制因素，发现沿黄、中部干旱带和南部山区各有不同制约因素。
Green development is the reflection and innovation in comparison to the traditional development mode,research on the green development,especially for Ningxia with the lagging economic development and fragile ecology,is particularly important. Basing the data of 2013,model of entropy,modified topsis and obstacle degree were used to study the spatial variation and relevant influence factors of green development levels among the counties in Ningxia. The results were as follows: The internal differences of green development levels in Ningxia were obvious,the values of close degree in District of Xixia, Xingqing, Jinfeng and Yuanzhou were far higher than other regions; well,the ones of Hongsipu area, Yanchi County and Tongxin County were the worst,whose green development levels need to be improved urgently. The factors restricting the green development of Ningxia had showed regional differences,and on the whole,counties(districts) along the Yellow River in Ningxia,counties(districts) in the drought of middle Ningxia,and that in southern Liupan Mountain have different limiting factors respectively. Furthermore,corresponding ways and countermeasures had better be taken in those areas,providing the scientific basis for the green development of Ningxia.
