安徽省自然生产力分布状况研究

利用多年平均气候资料对安徽省的自然生产力进行了核算 ,并利用经济系数测算了经济产量。安徽省的自然生产力由北向南逐渐增加 ,经济产量最低约 63 13kg/hm2 ,最高可达 17194kg/hm2 。南北差异显著 ,东西之间的差异则不显著。淮河以南水分较充足 ,对农业生产限制作用较小 ;淮河以北水分不足 ,水分成为农业生产的限制因素 ,提高该地区的水分利用率可大幅度提高农业生产潜力。

Study on the Distribution of Natural Productivity in Anhui Province

The natural productivity in Anhui Province was calculated with the multi-annual means climatic data and transformed as economical output. The natural productivity was increasing from northern to southern part in Anhui, the lowest economical output was 6313kg/hm2 and the highest was 17194kg/hm2.The difference of productivity was remarkable between southern and northern, and it was not remarkable between eastern and western. The moisture is sufficient in the southern area of Huaihe River, and had small limit-function in agricultural production.On the contrary, the moisture is insufficient in the north area of Huaihe River,and moisture is becoming the limiting factor to agricultural production. Enhancing the using efficiency of moisture will increase the agricultural production potential greatly.
