【摘要】 云南水能资源丰富,是我国重要的水电基地,水电开发具有综合效益好、比较成本低的显著特点,可极大地拉动当地的经济社会发展。电站建设涉及面广,需要解决的问题多,移民就是其中历来困扰水电开发建设的难题之一,移民搬迁贯穿于电站建设全过程,是水电开发不可分割的重要组成部分。随着社会的进步,以人为本观念的渗透,科学、有效地为水电开发移民选择理想的安置地,让移民真正从水电开发中受益已显得越来越重要。本文以拟建的怒江流域梯级电站中的六库电站为例,探讨采用GIS的空间叠置分析、缓冲区分析、网络分析等空间分析技术为移民寻找适宜居住的最佳搬迁地。安置区的选择,我们主要考虑以下因素:(1)靠近集镇或主要交通线,便于各类配套实施的建设及对外交往;(2)充裕的适宜开发的土地资源和水源条件;(3)坡度小于25度的区域;(4)安置区最好在本县,与所在区域居民语言相通,传统习俗相近便于沟通交流,有认同感;(5)安置区选择与自然保护区、国家重点建设规划用地不冲突。更多还原

【Abstract】 Yunnan Province is rich in hydroelectric resources and is an important hydroelectric base of China.Several major advantages of developing hydroelectricity,including very good overall benefits and lower developing costs,make hydroelectric development an obvious opportunity for promoting local socioeconomic development in Yunnan.However,because a lot of socioeconomic factors are involved in the building of power stations,there are many problems which need to be solved,among which the resettlement of the affected residents is one of the most difficult problems.Since resettlement will deeply affect the life of many people,it merits serious and in-depth consideration throughout development process.As the development of human becomes the primary value of the society,using scientific methods to select proper places to resettle the affected residents and make it possible for the residents to benefit from the hydroelectric development is becoming more and more important for the decision makers.Using the development of the Liuku Power Station as a case study,this paper explores the methods of using Geographic Information Systems to support the searching of resettlement sites.It demonstrates how spatial analysis methods,including overlay analysis,buffer analysis and network analysis,can be employed to evaluate locations and find the best locations for resettlement.Five major factors considered in the siting process include:1) transportation accessibility:close to the existing market town or major roads;2) good soil conditions and ample water resource for agriculture;3) areas with slope less than 25° for housing construction;4) better to be within the same county,for easier cultural adaptation;and 5) no conflicts with natural protection areas or National Key Construction projects.Analysis results are then presented and discussed.更多还原
