摘　　要：天山自然资源丰富，是新疆人民世世代代赖以生存和发展的天然宝库，野果林生态系统是其重要的组成部分，也是我国干旱区面积最大、种类组成最丰富的珍稀残遗阔叶林生态系统。它不仅在我国农林牧业的发展史中发挥了重要作用，而且更是今后可持续发展的生物资源基因库。天山野果林生态系统受损的原因，主要来自人类活动的影响，其结果表现为：在土地利用及开发过程中，存在农林牧争地等问题，致使野果林面积不断缩小；生物种类减少、资源量下降；土地退化日趋严重。The rich natural resource in Tianshan Mts.is very important to local people's living and development generation by generation. Wild fruit forest ecosystem is one of an important part of it. Wild apple (Malus sieversii) and wild walnut (Juglans regia) have been listed as Class II of state endangered plants. The abound biodiversity in Ili wild fruit forest is an important bio-gene pool that is essential to human's living and development in the future. According to many years' investigation, the wild fruit forest ecosystem in Tianshan Mts. in Xinjiang is suffering losses from activities of beings, and the area of wild fruit forest and species numbers have been reduced, which have caused land degeneration.
