The difference and vertical variability of the major nutrition elements contents in Carex lasiocarpa wetland soil and farmland soil are studied. The results show that the major nutrition elements contents in Carex lasiocarpa wetland soil are much more than those in farmland soil (except for total K content of surface layer), in which the contents of total P and total N in Carex lasiocarpa wetland soil are twenty more than those in farmland soil.

The difference and vertical variability of the major nutrition elements contents in Carex lasiocarpa wetland soil and farmland soil are studied. The results show that the major nutrition elements contents in Carex lasiocarpa wetland soil are much more than those in farmland soil (except for total K content of surface layer), in which the contents of total P and total N in Carex lasiocarpa wetland soil are twenty more than those in farmland soil. The vertical variability of Carex lasiocarpa wetland soil is notable, more than 40%, in which the variability coefficient of total N is highest, reaching 81.32%. But the verticality variability of farmland soil is not notable, less than 24%, mostly due to the water condition and the organic matter content.

以三江平原毛果苔草湿地及其开垦后的农田为研究对象 ,探讨了湿地开垦前后土壤中主要营养元素含量差异及垂直分异。结果表明 ,毛果苔草湿地土壤中主要营养元素含量要远高于农田土壤中营养元素含量 (土壤表层 K元素除外 ) ,其中 ,全 N含量相差 2 0多倍 ;毛果苔草湿地土壤中主要营养元素的垂直分异显著 ,都在 4 0 %以上 ,其中全 N含量的变异系数最高 ,达到 81.32 % ,而农田土壤中主要营养元素的垂直分异不太显著 ,都在 2 4 %以下 ,主要受水分条件和有机质的含量控制
