摘    要:通过对泥质海岸防护林土壤酶活性和理化性质关系的研究得出:(1)四种土壤酶(蔗糖酶、碱性磷酸酶、脲酶、蛋白酶)与土壤水稳性团粒含量、容重、孔隙率、有机质含量、盐分含量、全氮含量、速效磷含量、pH值有着密切的关系,而与物理性粘粒含量、含水量、速效钾含量不相关;(2)通过典型相关分析,土壤酶与理化性质之间关系密切,第一对典型变量的相关系数达0.9443。在土壤酶中起主要作用的是脲酶和蛋白酶,在理化性质中

关 键 词:泥质海岸  防护林  土壤酶  典型相关  理化性质

Abstract:Through studying the relationship of soil enzyme activities and physical and chemical properties in the areas of silting coastal protective forest,the results are as follows:(1)There are close relations between the four soil enzymes(invertase, alkaline prosphatase, urease, protease) and soil granular structure content of water stability, unit weight, porosity, organic substances,salt content,total-N,available-p and pH, while there is no relation between these enzymes and physical clay particle content, water content and available-K of soil.(2)By typical correlation analysis, soil enzymes and physical, chemical properties have a very close relation. The correlation coefficient of the first pair of typical variable is 0.944 3.Urease and protease play an important role in soil enzymes, while in the physical and chemical properties of soil, unit weight and total-N are more important than other factors.(3)The paper gives not only the regression equations of the enzymes and physical,chemical properties of soil respectively, but also the simplified equations by stepwise regression.(4)Soil enzyme activities can be used as the indexes of evaluating site productivity.
Keywords:Silting coast  Shelter forest  Soil enzyme  Typical correlation
