城镇化与生态环境系统是一对交互耦合的耗散结构体,时时进行物质、能量或信息等转化和交换,会引起两个系统熵变及耦合发展。作为第一人口大省和农业大省,研究河南省城镇化与生态环境协同发展,是一个具有现实意义的命题。首先运用熵值法,计算出河南省2014年城镇化与生态环境系统的各自发展水平,然后运用象限图分类识别法划分两个系统的关系,并根据类型进行深入的剖析,最后提出不同地域在资源环境承载范围内发展城镇化的主要路径。研究表明:1全省18个地级市可划分为6种类型,其中城镇化严重超前1个,城镇化中度超前5个,城镇化轻微超前3个,城镇化轻微滞后2个,城镇化中度滞后6个,城镇化严重滞后1个;2城镇化与生态环境之间协同关系南北市际差异显著,呈现出梯度发展的特征;3豫西北城镇化发展超前现象值得警惕,豫东南城镇化发展速度需进一步加快。
Urbanization and ecological environment system are a pair of coupling dissipative structure,who convert and exchange material,energy and information from time to time,resulting in entropy change of the two systems.As Henan is a large agricultural province with the largest populationin China,it is of great significance to study its coordinated development between urbanization and ecosystem. Firstly,entropy evaluation method was used to calculate the developmental level of Henan's urbanization and ecological system in 2014.Then the relation type between them was examined by quadrant diagram classification method. Finally,the primary path was put forward to urbanization development in the affordable range of various areas.The research shows that:118 prefecture-level cities in Henan can be divided into 6 types,one of which is of serious advanced type of urbanization while 5 of which are moderately advanced,3 slightly advanced,2 are slightly delayed,6 are moderately delayed and 1lagged far behind; 2Remarkable differences exist in the relation of urbanization and ecological system between the north and the south,presenting the feature of gradation development; 3The advanced urbanization development phenomenon in the northwest of Henan demands attention and the development in the southeast needs to be accelerated.
