- Abstract:
-
In order to know the level of sustainable land use and main obstacle factors of agro-pastoral zone of northeast China, the evaluation index system was constructed from economic possibility, sustainability of resources environment and social acceptability including 21 indicators. The level of sustainable land use in Baicheng was evaluated and analyzed from 2005 to 2014 with improved TOPSIS method based on combination weight method and grey relational analysis. The results showed that the level of sustainable land use in Baicheng had been gradually improved from 2005 to 2014 with the comprehensive close degree increasing from 0.335 5 to 0.6 320. The level of sustainable land use had risen from lower level to higher level. In the long run, the obstacle degree of economic possibility reduced. And the obstacle degree of sustainability of resources environment and social acceptability increased. The natural population growth rate, green coverage rate of developed areas, grassland coverage, and the ratio of third industry output values to GDP were verified to be the key obstacles for further improvement of sustainable land use in Baicheng. The sustainable land use was continuously improved by controlling population growth, further adjusting the economic structure, strengthening land use management, effectively controlling grassland degradation and so on.
