中文摘要	对甘肃省定西市安家沟流域自然条件、生产现状、社会经济条件进行实地调查、分析和评价,并对流域内典型的农林复合模式分别从其结构、组成、功能、经济投入和产出、形成背景等方面进行了调查、分析和评价,从中筛选出较适合该地区不同立地条件下的农林复合模式.并按各模式投入产出性价比,结合不同农林复合生态系统的主要生态功能,进一步组合为5个比较典型的农林复合优化模式:陡坡地水土保持林模式、缓坡地退耕还林(草)模式、梯田地农林复合模式、房前屋后雨水集流庭院经济模式、侵蚀沟水土保持林模式.该流域优化模式将对干旱半干旱区农林草混交种类及合理搭配和优化复合模式的遴选提供可行的思路和借鉴.
英文摘要	Field investigation,analysis and evaluation of natural conditions,production situation and socio-economic status in the Anjiagou river basin of Gansu province were conducted,through comprehensive analysis and evaluation of the structure,composition,function,input-output performance,formation background of typical agroforestry ecosystem models in basin,then selected the appropriate agroforestry ecosystem models to adapt to different site conditions.According to every models input-output performance cost-effective and combining the main ecological function,five typical optimized combination of agroforestry models were selected as follows: model of water and soil conservation forest at steep sloping land,model of returning farmland to forest or grassland at gentle sloping land,model of agroforestry ecosystem at terraces land,model of rainwater collection around courtyard,model of water and soil conservation forest at gully erosion land.The optimized model in Anjiagou river basin would provide the way and reference for crops,trees,grass mixed-type and reasonable combination,selection of optimized compound model in arid and semi-arid regions.
