农地利用效益协调度空间差异分析——以湖北省为例

Spacial Different Analysis on Coordination Degree of Agricultural Land Usage Benefits:Taking Hubei Province as Example

为了测度农地利用社会经济效益和生态环境效益之间的协调度,利用熵值法和灰色系统理论模型对湖北省各地区2001～2009年的农地利用效益协调度进行了研究。结果表明,湖北省各地区的农地利用效益协调度差异性很大,位置偏远且经济不发达的地区协调度低,沿长江区域的协调度比其他地区偏低,武汉城市圈区域的协调度比其他区域高,其中省直管市的协调度好。农地利用只有在社会经济效益和生态环境效益协调发展下才能实现土地利用综合效益的最大化。

The coordination degree between social and economic benefits and the ecological and environmental benefits of agricultural land usage in various areas of Hubei province in 2001~2009 was studied using the methods of entropy and gray system theory model.The results showed that the difference of different areas in Hubei province in coordination degree was very significant.The coordination degree was quite low in remote and undeveloped areas.The degree along Changjiang River area was lower than that in other areas.The degree in Wuhan metropolitan area was higher than that in other areas.The degree in province municipalities under the central government was the best.The research revealed that only coordinating the balance between the social and economic benefits and the ecological and environmental in the usage of agricultural land could maximize the benefit.
