摘  要:干旱沙区的农田防护林是人工绿洲的重要生态屏障,在防治风沙灾害、改善区域小气候、保障人民正常生产生活等方面发挥着至关重要的作用。为了解垦区农田防护林生态状况,以新疆石河子垦区150团为研究区域,构建了基于遥感生态和林学两个层面的评价指标体系,使用Landsat 8 OLI遥感数据提取了农田防护林遥感生态指标,并采用层析分析法对该地区的农田防护林生态状况进行等级划分和制图。同时,考虑了农田防护林的布局和实际树种情况,对150团的农田防护林生态状况进行了分析。结果表明:150团的农田防护林生态状况中等,其中生态状况表现为优的林带占总林带的21.2%,生态状况表现为中等的林带占41.8%,生态状况表现为低的占30.9%,而生态状况较差的占6.1%;防护林布局基本合理,连接度和环度分别为0.4307和0.1444,林带走向合格率为61.6%。在南北方向,林网状况存在差异;防护林树种较少且搭配不合理。The farmland shelter forests in arid sandy area are important ecological barriers of artificial oasis,and play a vital role in preventing and controlling wind and sand disasters,improving regional microclimate and ensuring people’s normal production and life.In order to understand the ecological status of farmland shelter forests in reclamation area,by taking 150th Regiment of Shihezi Reclamation Area in Xinjiang as the research area,an evaluation index system based on remote sensing ecology and forestry was constructed.The remote sensing ecological index of farmland shelter forests was extracted by Landsat 8 OLI remote sensing data,and the ecological status of farmland shelter forests in this area was classified and mapped by analytic hierarchy process.Meanwhile,considering the layout and the actual tree species of farmland shelter forests,the ecological status of farmland shelter forests in 150th Regiment was analyzed.The results showed as follows:the ecological status of farmland shelter forests in 150th Regiment was moderate,among which the forest belts with excellent ecological status accounted for 21.2%of the total forest belts,the forest belts with moderate ecological status accounted for 41.8%,the forest belts with low ecological status accounted for 30.9%,and the forest belts with poor ecological status accounted for 6.1%;the layout of shelter forests was basically reasonable,the connectivity and ring degree were 0.4307 and 0.1444,respectively,and the qualified rate of forest belt direction was 61.6%.In the north-south direction,there were differences in forest network status;there were few tree species in the shelter forests and the collocation was unreasonable.
