基于GIS的延边州环城游憩地空间分布研究

利用GIS的缓冲分析、栅格分类等空间分析技术，对延边州环城游憩地的空间格局进行定量分析．结果显示：在距离分布上，延边州环城游憩地以延吉市为中心形成了内外2个环城游憩带；在方位分布上，延边州环城游憩地具有偏西与偏东密集的方位分布特点；在地形效应上，延边州的环城游憩地具有在低海拔地区沿河分布的特点．因地制宜地利用好地形、地貌等自然条件，减少地形效应的负面作用，调整和优化游憩地的空间结构是延边州环城游憩地今后发展应注意的问题．

A Study on the Spatial Distribution of ReSAM in Yanbian Based on GIS Techniques

By using GIS techniques including grid classifying and buffer analysis, we make the quantitative anal- ysis for the spatial distribution of ReSAM around Yanbian Korean Autonomous Prefecture. It is concluded that types of recreational spots distribute unevenly in Yanbian. In the terms of distance distribution, the recreation- al spots have formed two recreational belts around the distribution characteristics. In the terms of azimuthal distribution, the spatial distribution of ReSAM in Yanhian tends to in the western and eastern of the city. In the terrain effect, the spots have the characteristics of distribution in low altitude area along the river. In the future people should pay attention to the following aspects for the development of ReSAM in Yanbian. We should suit our measures to local conditions to make good use of terrain, topography and other natural condi- tions. It is necessary to reduce the negative effect of terrain effect. The spatial structure of ReSAM should be adjusted and optimized.
