摘要
研究了淤泥质海岸防护林降盐改土的功能 ,结果表明 ,淤泥质海岸防护林表土已脱盐 ,土壤中可溶性离子成份发生了很大变化 ,不具有典型盐渍土的特性 ,土壤含盐量与潜水矿化度密切相关 (r =0 .9940 ) ,并随季节变化表现出不同的变化规律 。
The paper is aimed to expound the function of reducing soil salinity of shelter-forest in silting coastal area. The results are as follows: the salinity of top soil under the shelter-forest reduced greatly, and the composition of dissoluble ions also changed. Therefore the soil had no typical salt-affected characteristics. There was a close relationship between soil salinity and mineralization degree of ground water ( r =0.994 0).In addition, there existed different rules during various seasons. Tree roots of the shelter-forest paid an important role on reducing salinity and improving soil.
