甘肃第一性生产潜力的地区分布及开发利用初探

A PRELIMINARY PROBE INTO DISTRIBUTION AND EXPLOITATION OF PRIMARY PRODUCTIVITY IN GANSU PROVINCE

本文用迈阿密模型和桑斯韦特模型估算甘肃自然植被的第一性生产力及地区分布，用瓦赫宁根方法估算甘肃主要在作物的最大产量及地区分布。在此基础上，提出了分区开发初级生产潜力的途径。

This paper estimates the primary productivity of natural vegetation in Gansu province by Mi-ami model and Thornthwaite memorial model, analyzes it’s regional distribution and calculatesthe maximum yield of main crops in various regions by Wageningen measurement. On the basisof the abovp data,the ways of how to exploit the primary productivity of each region are dis-cussed.
