【摘要】：水资源是基础性的自然资源,对经济社会的意义重大,中国位于季风气候区,水资源时空分配不均,总体表现出南多北少、东多西少的特征。经济的增长紧跟着而来的是水资源的虚耗和污染,导致水质越来越差,日益阻碍经济增长。深刻认识水资源可利用状况,对认识水资源现状、挖掘社会经济发展潜力意义重大。本文通过分析中国水资源可达性与经济的关系,对认识中国水资源分布规律,推动国民经济社会持续发展意义重大,以求为区域发展决策提供参考依据。本文提出水可达性-经济关系假说,认为水可达性与经济空间分布之间存在密切关系,研究分析中国水可达性与经济空间分布的关系,并根据其空间分布规律提出相应的对策。以下内容为文章主要结论:(1)水可达性-经济关系理论。通过空间数学统计方法分别分析水可达性与经济空间分布规律,利用数学方法分析发现水可达性与经济空间分布之间存在正相关关系。水可达性等级越高,地方经济发达程度越高。(2)水可达性在中国九大流域的分布规律。以九大流域为单元研究中国水资源可达性的空间分布规律,由于地形、坡度等自然因素的影响,水可达性区域分布差异巨大。结果表明以长江流域水可达性最为丰富,西北诸河流域和西南地区由于深居内陆,地势高峻,降水量稀少,水可达性最低。(3)探究中国经济空间分布规律。通过中国各地级市的GDP数据利用空间插值技术研究中国经济空间分布规律,并认为中国经济存在空间差异。地区经济发展呈现集聚现象,在不同区域内部出现核心经济地区带动区域发展。(4)中国水可达性与经济空间分布关系。本文利用空间统计方法,分别统计中国水可达性与中国经济空分布格局不同等级的面积、所占像元等信息,并利用回归分析方法分析水可达性和经济之间的关系,并分析表明在经济发达中心地区,水可达性的等级高,并在不同的区域地区出现水可达性-经济中心。
[Abstract]:Water resources are the basic natural resources, which are of great significance to the economy and society. China is located in the monsoon climate region. The distribution of water resources in time and space is uneven, showing that the south is more than the north and the east is more than the west. Economic growth is followed by waste and pollution of water resources, which leads to worse and worse water quality and increasingly hinders economic growth. It is of great significance for us to understand the present situation of water resources and tap the potentiality of social and economic development by deeply understanding the available situation of water resources. By analyzing the relationship between water resources reachability and economy in China, this paper is of great significance in understanding the law of water resources distribution in China and promoting the sustainable development of national economy and society, in order to provide a reference basis for regional development decision-making. This paper puts forward the hypothesis of water reachability-economic relationship, holds that there is a close relationship between water reachability and economic spatial distribution, studies and analyzes the relationship between water reachability and economic spatial distribution in China, and puts forward corresponding countermeasures according to its spatial distribution law. The main conclusions are as follows: (1) the theory of water reachability-economic relationship. The spatial mathematical statistical method is used to analyze the law of water reachability and economic spatial distribution, and it is found that there is a positive correlation between water reachability and economic spatial distribution by mathematical method. The higher the level of water accessibility, the higher the degree of local economic development. (2) the distribution of water accessibility in nine major watersheds in China. The spatial distribution of water resources reachability in China is studied with nine basins as a unit. Due to the influence of natural factors such as topography and slope, the regional distribution of water reachability varies greatly. The results show that the Yangtze River basin is the most abundant in water reachability. The northwest Zhuhe River basin and southwest China have the most abundant water reachability, because of their deep inland, high topography, rare precipitation and lowest water reachability. (3) to explore the spatial distribution law of China's economy. The spatial distribution of Chinese economy is studied by using the spatial interpolation technique based on the GDP data of different prefectural cities in China, and the spatial difference of Chinese economy is considered. The regional economic development presents the phenomenon of agglomeration, and the core economic area drives the regional development in different regions. (4) the relationship between the water accessibility and the spatial distribution of the economy in China. In this paper, the spatial statistical method is used to calculate the area and pixel of different grades of water reachability and the spatial distribution pattern of Chinese economy, and the relationship between water reachability and economy is analyzed by means of regression analysis, and the relationship between water reachability and economy is analyzed by regression analysis. The analysis shows that the water reachability level is high in the developed economic center area, and the water reachability-economic center appears in different regions.
