摘　　要：农田防护林健康对维护绿洲生态安全、减少风沙灾害、改善局地小气候、提高农作物产量等具有重要的意义。综合运用熵值法和层次分析法确定指标权重,基于驱动力-压力-状态-影响-响应(DPSIR)模型对河西走廊农田防护林健康状况进行了评价。结果表明:(1)河西走廊农田防护林整体上处于亚健康水平,瓜州县、酒泉市肃州区、嘉峪关市和临泽县的农田防护林处于健康水平,民勤、民乐、高台和阿克塞的农田防护林处于不健康水平,其余区县农田防护林处于亚健康状态。(2)林带连续性、疏透度、修枝情况和地区经济收入是驱动区域农田防护林健康状况的关键因素。The health of farmland shelter belt has an important impact on maintaining oasis ecological security,reducing wind and sand disaster,improving local microclimate and increasing crop yield.We comprehensively used entropy method and analytic hierarchy process to determine the indicator weight and evaluated the health status of farmland shelter forest in Hexi Corridor based on DPSIR model.The results showed that:(1)The farmland shelter belt in Hexi Corridor is at the sub-health level on the whole,of which only the farmland shelterbelts in Guazhou county and Linze County is at the healthy level,the farmland shelter belt in Minqin County Aksay Kazak Autonomoas County is at the unhealthy level,and the farmland shelter belts of 15 districts and counties that are at the sub-health status,accounting for 78.95%of the total districts and counties.(2)The forest belt continuity,the degree of thinning,pruning situation and regional economic income are the key factors to drive the health status of regional farmland shelter belt.
