Abstract

Abstract: In order to know the impact of soil moisture on the stability and productivity,the plantations located in flatland and low-lying land in Maowusu sandland were selected to do comparative analysis on corresponding characteristics with a view to providing reference for the Maowusu Sandland afforestation design and site selection.The results show that the soil moisture content,total phosphorus and total kalium content of low-lying land were all significantly higher than flatland,but the soil moisture content played a dominant role in the formation of the characteristics of the plantation;the tree height growth,forestry productivity and ramet number of low-lying land were significantly higher than flatland,and its plantation age structure belongs to a growing(or stable) one,but the flatland belongs to declining type.Thus,forestry productivity and plantation stability have good consistency,as the soil moisture contentis higher,the forestry productivity and plantation stability of low-lying land become better,as the soil moisture content is lower,the forestry productivity and plantation stability of flatland become worse.

Key words: Hippophae rhamnoides subsp.sinensis, forestry productivity, population stability, soil moisture content, population structure, growth pattern
