摘　　要：为解决林权制度改革后绿洲区农民经营防护林的成本效益均衡问题,从绿洲防护林结构和防风效应的原理出发,推演大范围绿洲防护林结构管理的要点,提出适用于农村产权制度的绿洲防护林防风效应评价参数——立木蓄积量指数。立木蓄积量指数是单位面积绿洲耕地所拥有的防护林立木蓄积量,该参数的大小可以较贴切地表达绿洲防护林防风效应的优劣:树木个体越大、保存株数越多,防护作用越好,立木蓄积量指数越大;可以方便地与常规林业、农业统计指标衔接,分解到县、乡、村、户,方便与林业补贴、惠农政策补贴挂钩;也可以为绿洲防护林存量管制制度提供依据,是符合新林权制度下农村防护林动态管理需要的一个实用参数。To solve the cost-benefit balancing problem of the oasis farmers operating shelterbeh forest tenure reform, from the oasis of sheherbelts structure and wind effects principle, the points deduction a wide range of oasis protection forest structure management, the rural property rights system shelterbelt windproof benefits evaluation parameter： stumpage index. The stumpage index definition is the protection forest growing stock volume per unit area oases have. The size of the parameters can be more aptly express the pros and cons of the windproof benefits ： the larger the individual trees, save the trees more,the better the protective effect, the greater the index of stumpage. It can easily converge with conventional forestry, agriculture statistical indicators, broken down to the county, township and village households, convenient and forestry subsidies, linked to the preferential agricultural policy subsidies. Oasis protection forest inventory control system to provide the basis, in line with the new forest right system rural shelterbehs under dynamic management requires a practical parameters.
