Abstract

This article by the quadrat survey based on western Tumochuan three research plots , three were pattern type , pattern intensity and pattern of scale , plants and soil salinity response relationship . The main findings are as follows : ( 1 ) three of 14 study sites , the vast majority of halophytes population pattern type aggregated distribution the only alkali Artemisia currents park and I realized cap for uniform distribution of Altai Gouwa spent currents The north-south direction of the park as evenly distributed. The population gathered strength becomes dominant alkali Artemisia , salsa, Puccinellia tenuiflora population , gathered strength high population pattern . The three kind Mediterranean stream Park population pattern size larger than I realized cap and Kazakh prime village area, and I realized that the size of the population pattern tegmental area larger than the scale of the the Kazakh prime village populations pattern , size of its pattern of soil salinity the impact . (2) the alkali Artemisia , salsa, alkali land Saussurea Puccinellia tenuiflora salt ion salt is higher than the L. chinensis , Leymus Yinchenhao of . K Na, Cl - ions and salt tolerance in plants closely related to plants , high K Na, Cl- concentration , the salt tolerance of plants strong . (3) the western plains Tumochuan halophyte salt content of the body change with the change of soil salt content . And the plants salt content variations than variations of soil salt content , the stronger salt tolerance in plants , plant salt luffing greater the greater the range of plant salt tolerance , indicates that the plant is more enriched soil corresponding ions. Adapt to the performance of the distribution of plant populations and salinization of soil plant communities on the population of the three regions gradually reduced with the increase in the salt content of the sample plots , the life form of plant populations showed a similar phenomenon , similar increase of plant populations , lower cover and other features.
