摘要: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。

Abstract: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 wasstudied 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.

随着经济的快速发展,人口的增多和城市化进程的加快使土地的供需矛盾越来越突出。在保持1.2亿hm2耕地红线的基础上,如何针对有限的土地资源,在土地利用过程中促进人口、资源及环境的协调发展是学术界以及各级政府一直关注的问题。如今已有很多学者进行了这方面的研究。梁红梅等[1]以广州市为例,通过计算协调度分析了土地利用效益耦合度演化过程。曹堪红等[2]以广州市和深圳市为例,对沿海地区土地利用效益的耦合规律进行了比较研究。李瑞华等[3]以河南省为例,对农地利用社会经济效益和生态环境效益变化趋势指数和协调度进行了研究。周裕丰等[4]以广州市为例,用协调度模型对农村土地利用协调度进行了分析并提出了相应的对策建议。……
