【摘要】：隨著我國(guó)社會(huì)經(jīng)濟(jì)的快速發(fā)展,居民可自由支配收入和休閑時(shí)間不斷增加,旅游在人們休閑活動(dòng)中的地位越來(lái)越重要。重慶市夏季休閑旅游發(fā)展迅速,外出旅游人數(shù)不斷攀升,但是用地不足,接待能力不夠,以及缺乏科學(xué)規(guī)劃所帶來(lái)的環(huán)境問(wèn)題已成為旅游可持續(xù)發(fā)展的阻礙。本文選取重慶市為研究對(duì)象,收集區(qū)域地形、水文、氣候、土地覆被、社會(huì)經(jīng)濟(jì)等基礎(chǔ)數(shù)據(jù),通過(guò)查閱相關(guān)資料,以此為基礎(chǔ)構(gòu)建旅游用地選址評(píng)價(jià)指標(biāo)體系,然后基于GIS技術(shù),計(jì)算獲得地形條件、水文條件、氣候條件、土地覆被條件和社會(huì)經(jīng)濟(jì)條件柵格數(shù)據(jù)集,對(duì)研究區(qū)進(jìn)行旅游用地單因子適宜性評(píng)價(jià),采用層次分析法確定各評(píng)價(jià)因子權(quán)重,然后進(jìn)行加權(quán)疊加分析,并采用自然裂點(diǎn)法對(duì)研究區(qū)旅游用地綜合適宜性進(jìn)行分級(jí),在分級(jí)基礎(chǔ)上,從最適宜區(qū)域里劃分出四面山、金佛山、白馬山、大仙女山、黃水、巫山和大巴山7個(gè)最適宜片區(qū),以金佛山片區(qū)為為例,采用更大比例尺的地形數(shù)據(jù)和土地利用現(xiàn)狀數(shù)據(jù)進(jìn)一步限定,得到更合適的選址方案。研究結(jié)果表明： (1)不適宜地區(qū)面積為31930.59km2,占研究區(qū)總面積的38.12%,主要分布在河谷、中部丘陵、地勢(shì)較高的川東平行嶺谷、東北部低山地區(qū)以及東南部的喀斯特平原等地。這些地區(qū)雖然地形條件較好,但受水文、氣候、土地覆被和社會(huì)經(jīng)濟(jì)條件很大程度的限制。 (2)較不適宜地區(qū)面積為32358.14km2,占研究區(qū)總面積的38.63%,主要分布在丘陵地區(qū)、四川盆地東部的幾大平行嶺谷間的槽壩地帶及東南、東北和中部的部分過(guò)渡地帶。這些地區(qū)地形和社會(huì)經(jīng)濟(jì)條件好,地被指數(shù)高,受水文、氣候條件的較大限制。 (3)較適宜地區(qū)面積為15821.48km2,占研究區(qū)總面積的18.89%,主要分布在東北、東南和南部的中山地區(qū)。這些地區(qū)地形條件和社會(huì)經(jīng)濟(jì)條件較差,地被指數(shù)較低,但水文條件較好,氣候舒適期較長(zhǎng)。 (4)最適宜地區(qū)面積為3649.43km2,占研究區(qū)總面積的4.36%,主要分布在東北、東南和南部的大巴山、巫山、武陵山及大婁山的高山地區(qū),這些地區(qū)地形條件差,地被指數(shù)低,社會(huì)經(jīng)濟(jì)條件不發(fā)達(dá),但水文條件和氣候條件是所有分區(qū)中最好的。 (5)選址方案的適宜區(qū)面積為22.07km2,占金佛山片區(qū)總面積的12.14%,主要分布在金佛山片區(qū)的東部和南部,北部和西部有零星分布,這些地區(qū)滿足地形數(shù)據(jù)和土地利用現(xiàn)狀數(shù)據(jù)的限定條件。
[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.
