| 摘 要： | 本文以湖北大别山区为例,提出了自然条件复杂,资料缺乏的山区土地资源第一性生产力的估算方法,并计算了湖北大别山区土地资源的生产力。即在土地资源带及类型(组合)区划分的基础上,以资源类型(组合)区为基本单元,通过典型地区抽样获取资料,运用多种数学模型测算,并经过综合判定,求得各类型(组合)区,资源带主要作物的第一性生产力。

| Abstract: | In this paper, a method estimating primary productivity of land resource in mountainous region has been put forward. It can be summarized as th following.On the basis of classification of agrieultrual land resource zone and type district, land resource type district is consiidered as the basic calculation unit. Using some mathematics models, such as GM(1,1 )model of grey system of cycle ratio model and so on ,the primary productivities in different resource zones and different type districts can be got by comprehensive judgement. |
