| 摘 要： | 土壤含水量的多寡直接影响到作物的正常生长发育和产量形成。因土壤水分测定劳动强度大,工序繁杂,无论从时间序列的连续性,还是从空间分布的合理性,各地都缺乏完整资料。所以前人在单点土壤水分变化规律和通过自然降水进行土壤水分分区研究较多。

| Abstract: | In order to know overall the regularity of soil moisture variance in Shaanxi Province and to provide scientific basis for rational distribution of agriculture,the soil moisture has been classified by the method of fuzzy cluster and zoned by center condensation stepwise cluster on the basis of analysing variation of difference between precipitation and evaporation in time and space.The zoning index and method of soil moisture has been explored initially. |
