| 摘 要： | 本文从能量学观点，对山东、浙江沿海潮土及滨海盐渍土进行了不同土水势条件下，土壤持水性与主要影响因素的相关分析和通径分析．结果表明：＜０．０２ｍｍ物理性粘粒与土壤盐分含量是影响土壤持水性的主要因素。其中，３０～５０ｋＰａ吸力下，土壤盐分含量起着决定性作用。

| Abstract: | The soil moisture retention of chao soil and shore saline soil in Shandong andZhejiang province was measured by pressure membrance apparatus. Correlation and pathanalysis was applied for examining its main infuence factors. The results was shown thatphysical cay with diametter<0. 02mm and soil salt content was the main infuence factorsthat effect the water retention capability of soils. And when soil suction was 30-50kpa,the salt content of soil will be the vital factor. |
