摘要
高寒沙地优势防护林筛选对于治理沙化土地,减少沙漠化的危害具有重要意义。基于青海共和荒漠生态系统定位研究站的观测数据和专家知识,利用层次分析法(Analytic Hierarchy Process,AHP)对不同防护林类型的生态服务功能进行评价,选择出高寒沙地主导生态服务功能优化的防护林类型,结果表明,从流动沙丘的中间锦鸡儿、柠条和沙蒿中选择中间锦鸡儿和柠条,从丘间地的赖草、柽柳、乌柳、乌柳+沙柳混交林、乌柳+小叶杨混交林中选择乌柳和乌柳+沙柳混交林可以更好地实现其生态服务功能价值。
The selection of the most suitable shelter forest types for alpine sandy land has great significance to controlling sandy land in this region.In this study,ecological service function assessment of different alpine sandy land shelter forest types was conducted in order to select the most suitable shelter forest type for this special area.Analytic Hierarchy Process(AHP)was used to evaluate the ecological service function of alpine sandy land shelter forest based on data obtained from Qinghai Gonghe Desert Ecosystem Research Station and expert knowledge.Selections of Caragana intermedia and Caragana Korshinskii from Artemisia desertorum,Caragana intermedia and Caragana Korshinskii on moving sand dune and Salix cheilophila and mixed forest of Salix cheilophila with Salix psammophila from Leymus secalinus,Tamarix chinensis,Salix cheilophila,mixed forest of Salix cheilophila with Salix psammophila and mixed forest of Salix cheilophila with Populus simonii on the interdune were taken as the most suitable shelter forest types for alpine sandy land.
