摘要: 农业是按着人类的经济目的而进行的生物生产。农业生物有其固有的生命活动规律,它受当地自然环境条件,诸如气候、地形、土壤等因素的影响与制约,具有明显的地域性;同时,它又是经济再生产,故受到经济规律,诸如社会经济条件、生产水平、人力物力以及社会需要等影响与制约。

Abstract: In this paper, by analysing some basic factors the authors point out that some main climatological factors, such as light, temperature and mois ture, obviously affect the yields of crops, and then propose a agroclimatic model for the output of five crops as to evaluate regional agroclimatic resources. Under conditions of the present climate, the three correct coefficients in this model, interception of leaf area for light, temperature and moisture, are given. On the premise of analysing the climatological yields of crops and their variances, in order to develop the advantages of climate, the main regions of croping are drawn out. After calculating adjustment coefficients for planting area of five varieties of Crops in 45 counties, the authors plot the composite distribution map of crops.
