国家级水利风景区空间分布特征及可达性研究

A study of space distribution characteristics and the accessibility of national water conservancy sights

水利风景区作为发展水利旅游的载体,是一种资源开发与保护的模式。文章利用GIS空间分析技术和空间计量地理方法,以省域为单位,对国家级水利风景区的空间分布格局进行结构性、均衡性和组合性分析,并基于谷歌地图测算其交通可达性。结果表明:中国国家级水利风景区(1)呈凝聚分布态势,空间分布均衡性差,空间分布高密度区集中在东部沿海,低密度区分布在东北三省和西部地区。(2)其分布与河流和降水量密切相关,集中分布在黄河干支流、渭河流域、淮河流域、长江中下游等区域,以及400mm年降水量分界线以南地区。(3)其可达度均值为261.89 min,64.53%的可达度在240min以内,全国分布差异十分明显。最后对不同区域提出相应的发展建议。

Water Conservancy Sights are the base of developing water conservancy tourism,which also the mode of resource utilization and protection.By means of GIS analysis technique and measurement method of geography,the paper takes China's 719 National Water Conservancy Sights as the research object to analyse the structural,equilibrium and combination of distribution pattern. It uses Google map search platform to calculate the accessibility of the National Water Conservancy Sights.The results show that: First,National Water Conservancy Sights appear agglomeration and imbalanced distribution,highly concentrating in the eastern coastal,low density distribution in the northeast and western regions. Second,the distribution of National Water Conservancy Sights is closely related to the distribution of rivers and precipitation,focusing on the Yellow River River,Weihe River,Huaihe River,downstream of Yangtze River.There also spread the south of 400 mm precipitation boundary. In addition,the average accessibility of National Water Conservancy Sights is 261.89 min,64.53% degrees of National Water Conservancy Sights within 240 min. The difference of accessibility in the country is very obvious.Finally,this paper puts forward some suggestions for the different distribution types.
