| 摘 要： | 易地扶贫搬迁是对生活在恶劣环境中的贫困人口采取的扶贫举措。泸水县尚有大量人口需要易地搬迁解决贫困问题,泸水县特殊的峡谷地理环境,使安置地的选择成为棘手的问题。将GIS技术应用于扶贫易地搬迁地选择中,可以方便地找出适宜的搬迁居住地,为当地政府易地安置提供决策参考依据。安置区的选择,主要考虑以下因子：交通便利、土地资源丰富、水源丰富、坡度较为平缓、海拔较低,避开地质灾害隐患点和自然保护区等。通过GIS技术,将上述因子图层叠加后找到适合的安置地。结果表明：泸水县难以找到成片的面积较大的安置区,安置区呈零星状分布在各个乡镇。

| Abstract: | The relocation of ex-situ pro-poor is a poverty reduction measure to help the poor people who live in harsh environments. A large number of people need to solve the problem of poverty by ex-situ removal in Lushui. Placement choice becomes a thorny issue because of the special canyon geographical environment in Lushui. It will find easily suitable relocation residence, and can provide decision-making reference in relocation for government, if GIS technology is applied to the choice of ex-situ removal for anti-poverty. The main considerations factor about choice in the resettlement areas include： convenient transportation; rich in land resource and water; gentle slope; lower altitude; avoid potential geological disasters and nature reserve etc. The suitable resettlement areas will be found after layers obtained by the above factors are overlapped through GIS technology. The results show it is difficult to find a larger piece of resettlement areas in Lushui, the resettlement areas are sporadic-like distribution in various townships. |
