POPULATION CHARACTER OF ALHAGI SPARSIFOLIA AND PLANT COMMUNITY SUCCESSION
疏叶骆驼刺种群性质与植物群落演替

Alhagi sparsifolia is widely distributed in lowland saline meadows of Xi- njiang desert region. It occurs as a dominant or an accompanying species in plant communities.In saline meadows. the floristic composition and the po- pulation character of A. sparsifolia varies with the changes in soil water and salt conditions. Under the influences of human activities. more serious chan- ges happen upon soil water and salt conditions.As a consequence. the flori- stic composition of saline meadows become unstable. The population charac- ter of A. sparsifolia may be used as an indicator for succession state of plant community.This function is of significance to water and land use in that re- gion.
