摘　　要：选择和田地区特定区域,研究农田防护林树种组成、混交情况、年龄结构等,分析其经营现状及存在的问题.结果表明：洛浦县农田防护林存在混交林比例过低,仅占防护林总面积的11.29％;林龄结构不合理,大多集中于7～16年；防护林树种少、经济价值低；林网规格与保护对象不适应等现实问题.并针对问题提出加强宣传和指导营造混交林；利用防护林防护成熟、工艺成熟和经济成熟期的时间差调整防护林林龄结构；引入夏橡、水曲柳、黑核桃等经济价值高的树种营建混交林带,并积极营建生态经济型防护林；根据保护目标植物适时调整林网大小等解决对策.Selected specific areas in Hetian District, studied the tree species composition of farmland shelterbelt, mixed condition, structure of age, and analyzed the operating status and problems. The results showed that： the farmland shelterbelt of Loupu existed practical problems, mixed low proportion, accounting for only 11.29% of the total area shelter; structure of forest age was irrational, mostly concentrated in the 7 to 16 year; shelter trees species was few and economic value was low; specification of windbreak net and object of protection was not adapted. In view of the problems put solutions： Strengthen the publicity and guidance to create a mixed; Use of sheherbelts protection mature, mature technology and economic maturity of the time difference to adjust structure of forest age. The introduction of Quercus robur, Fraxinus mandshurica and black walnut and other species of high economic value construction mixed forest zone, and actively build ecological economical shelterbelt; According to conservation objectives plant timely adjusted the size of windbreak net forest, and so many measure on.
