延吉市环城游憩地空间结构研究

Study on the Spatial Structure of Recreational Spots around Yanji City

边境城市的游憩资源发展研究是边境地区少数民族城市社会经济可持续发展研究的一个重要方面。基于GIS空间分析技术,对延吉市环城游憩地进行空间距离、时间距离分析和空间方位、地形效应分析,得出延吉市各类型游憩地在方位分布上具有南部密集、西部分散的不均匀分布特点,距离市区3～6 km的范围的"带状"区域为延吉市环城游憩地发育最为成熟的区域,40 min单程车程为延吉市的最佳环城游憩半径;延吉市环城游憩地受地形阻隔作用明显,短途短时的环城游憩圈层结构沿中高等级公路走向延伸,环城游憩地这一空间结构形态反映出延吉市环城游憩地建设自发阶段的市场特点,环城游憩地空间结构有待进一步调整和完善。

The development of recreation resources in the border cites have great significance in the research of the socio-economic sustainable development of the frontier minority urban. Through the spatial analysis including space distance, temporal distance, space position and landform effect of recreational spots around Yanji City based on GIS techniques, we study the recreation space structure of the medium and small border cities under the geopolitical environment perspective of the Northeast Asia. The results show that types of recreational spots unevenly distributed in the western and southern of the city. At the region of 3 - 6 km around the city, the recreational spots are developing very well, and 40 minutes temporal cost by car is the best recreation radius around Yanji City. What is more, the landform effect of recreational spots and the structure of recreational ring around Yanji City showed its characteristics of spontaneous market, the recreational spatial structure of Yanji City should be further readjusted and improved.
