摘要
在建立人地关系地域系统耦合度评价指标的基础上,运用灰色关联分析,以2005年渭河流域干流地区48个区县市为基本研究单元,分析了渭河流域人地关系地域系统耦合的主要因素和耦合度的空间分布。研究结果表明:流域人地关系地域系统是一个复杂的系统,各指标要素之间存在着错综复杂的关系,生活水平和城市化水平是影响本地区资源环境的主要方面,SO2、COD排放量、地区年用水量、已建设用地是目前制约本地区社会经济发展的主要因素;渭河流域耦合度的空间分布与该地区的社会经济水平呈正相关,2005年本地区耦合度的空间分布以拮抗型为主,低水平耦合次之。
Firstly,the evaluation index to coupling degree of man-land relationship areal system was established.Then,based on the data of 48 counties in Wei River Basin in 2005,using methods of qualitative and quantitative analysis and grey correlative analysis,the main factors of coupling and the distribution of coupling degree of man-land system in Wei River Basin were researched.The results showed：（1） It was a complex system about man-land relationship areal system in river basin.There were intriguing relations in the various basic factors and the coupling mechanism.We selected 21 indexes of socio-economic and 11 indexes of resource-environment to reveal the main factors of coupling in Wei River Basin.It could be seen that the living standard and the urbanized level were the main momentums to affect resource-environmental system.Meanwhile,SO_2 emission,COD emission,water consumption in local places and constructed land were the main factors to restrict the development of socio-economic.（2） There was a positive correlation between the special distribution of the coupling degree and the socio-economic level of man-land relationship areal system in Wei River Basin.It could be divided into four types,that were harmony,amelioration,confliction and low-level coupling.In 2005,the confliction was the dominant type,followed by low-level coupling in this area.
