【摘要】：随着我国社会经济的快速发展,居民可自由支配收入和休闲时间不断增加,旅游在人们休闲活动中的地位越来越重要。重庆市夏季休闲旅游发展迅速,外出旅游人数不断攀升,但是用地不足,接待能力不够,以及缺乏科学规划所带来的环境问题已成为旅游可持续发展的阻碍。本文选取重庆市为研究对象,收集区域地形、水文、气候、土地覆被、社会经济等基础数据,通过查阅相关资料,以此为基础构建旅游用地选址评价指标体系,然后基于GIS技术,计算获得地形条件、水文条件、气候条件、土地覆被条件和社会经济条件栅格数据集,对研究区进行旅游用地单因子适宜性评价,采用层次分析法确定各评价因子权重,然后进行加权叠加分析,并采用自然裂点法对研究区旅游用地综合适宜性进行分级,在分级基础上,从最适宜区域里划分出四面山、金佛山、白马山、大仙女山、黄水、巫山和大巴山7个最适宜片区,以金佛山片区为为例,采用更大比例尺的地形数据和土地利用现状数据进一步限定,得到更合适的选址方案。研究结果表明： (1)不适宜地区面积为31930.59km2,占研究区总面积的38.12%,主要分布在河谷、中部丘陵、地势较高的川东平行岭谷、东北部低山地区以及东南部的喀斯特平原等地。这些地区虽然地形条件较好,但受水文、气候、土地覆被和社会经济条件很大程度的限制。 (2)较不适宜地区面积为32358.14km2,占研究区总面积的38.63%,主要分布在丘陵地区、四川盆地东部的几大平行岭谷间的槽坝地带及东南、东北和中部的部分过渡地带。这些地区地形和社会经济条件好,地被指数高,受水文、气候条件的较大限制。 (3)较适宜地区面积为15821.48km2,占研究区总面积的18.89%,主要分布在东北、东南和南部的中山地区。这些地区地形条件和社会经济条件较差,地被指数较低,但水文条件较好,气候舒适期较长。 (4)最适宜地区面积为3649.43km2,占研究区总面积的4.36%,主要分布在东北、东南和南部的大巴山、巫山、武陵山及大娄山的高山地区,这些地区地形条件差,地被指数低,社会经济条件不发达,但水文条件和气候条件是所有分区中最好的。 (5)选址方案的适宜区面积为22.07km2,占金佛山片区总面积的12.14%,主要分布在金佛山片区的东部和南部,北部和西部有零星分布,这些地区满足地形数据和土地利用现状数据的限定条件。
[Abstract]:With the rapid development of China's social economy, residents can freely dispose of their income and leisure time, and tourism plays an increasingly important role in people's leisure activities. Summer leisure tourism in Chongqing is developing rapidly and the number of people traveling out is rising. However, insufficient land use, insufficient reception capacity and environmental problems brought about by the lack of scientific planning have become obstacles to the sustainable development of tourism. This article selects Chongqing as the research object, collects the regional terrain, the hydrology, the climate, the land cover, the social economy and so on basic data, through consulting the related data, constructs the tourism land site selection evaluation index system based on this, Then based on GIS technology, the raster data sets of terrain, hydrology, climate, land cover and socio-economic conditions are obtained, and the single-factor suitability evaluation of tourist land is carried out in the study area. The weight of each evaluation factor is determined by analytic hierarchy process (AHP), and then the weighted superposition analysis is carried out, and the comprehensive suitability of tourist land in the study area is classified by natural crack point method. On the basis of the classification, the four sides of mountains are divided from the most suitable area. Jinfo Mountain, Baaima Mountain, Daxian Nu Mountain, Huangshui, Wushan and Daba Mountain are the seven most suitable areas. Take the Jinfo Mountain area as an example, use larger scale topographic data and land use status data to further limit. A more suitable site selection scheme is obtained. The results show that: (1) the area of unsuitable area is 31930.59km2, which accounts for 38.12km2 of the total area of the study area, mainly distributed in river valleys, hills in the middle, and parallel ridges in eastern Sichuan with higher topography. Low mountains in the northeast and karst plains in the southeast. These areas are limited by hydrology, climate, land cover and socio-economic conditions, although they are better. (2) the unsuitable area is 32358.14km2, which accounts for 38.63 of the total area of the study area. It is mainly distributed in hilly areas, the channel and dam areas between several parallel valleys in the eastern part of Sichuan Basin and some transitional zones in southeast, northeast and central part. The topography and socio-economic conditions of these areas are good, the land cover index is high, and it is restricted by hydrological and climatic conditions. (3) the suitable area is 15821.48km2, which accounts for 18.89 parts of the total area of the study area, mainly distributed in the Zhongshan area of northeast, southeast and south. The topographic conditions and socio-economic conditions of these areas are poor, the land cover index is lower, but the hydrological conditions are better, and the climate comfort period is longer. (4) the most suitable area is 3649.43 km2, which accounts for 4.36% of the total area of the study area. It is mainly distributed in the mountains of Daba, Wushan, Wuling and Dalou in the northeast, southeast and south of China. Land cover index is low, social and economic conditions are not developed, but hydrological and climatic conditions are the best of all subzones. (5) the suitable area of the site selection is 22.07km2, which accounts for 12.14% of the total area of Jinfushan, mainly distributed in the east and south of Jinfushan, and scattered in the north and west. These areas meet the requirements of topographic data and land use status data.
