摘要
基于Costanza市场估算法和相关系数检验法探究武汉市土地利用变化带来的生态服务价值与区域经济发展有无统计学意义上的相关性.将1996-2008年武汉生态服务价值与GDP做皮尔逊、斯皮尔曼、肯德尔相关系数检验,得到相关系数分别为0.90554,0.95055,0.82051,且均通过T值检验.研究结论表明:①武汉生态服务价值与GDP呈现出非常显著的正相关关系,说明武汉经济发展是相对持续和生态环保的;②水体和园林在武汉生态环境中占有重要组成作用,武汉生态服务功能的发挥主要依靠水体和园林;③湿地、农田的生态服务功能不容忽视.
The purpose of this paper is to explore the interrelationship between economy index and the ec- ological service value in Wuhan City, with the changes of land use from 1996 to 2008. The Costanza mar- ket estimation and correlation coefficient test were employed. The main results show that, the Pearson, Spearman and Kendall correlation coefficients are 0. 905 54,0. 950 55, 0. 820 51, and all of them go through the T value test. It was concluded that, 1there is very significant positive correlation between the ecological service value and GDP in Wuhan, which can describe the way the economy developed of Wu- han is relatively sustained ; 2water area and forest play an important role in Wuhan ecological environ- ment, and they undertake the main ecological function as well;3the ecological service value of wetland and farmland should not be ignored.
