Title: Comparison on Water Ecology of Plant Community,Artificial Grassland and Shrub Forest Land in Zhungeer Hilly Region
Abstract: The Zhungeer hilly region is located in the west part of the Ordos Plateau, Inner Mongolia, it is a key region for soil erosion control and eco environment restoration in the middle reach of Yellow River. On 20 August 2001, the transpiration characteristics of Thymus serpyllum community, Astragalia adsurgens cv. artificial grassland and Hippophae rhamnoides shrubs forest land were measured under natural conditions by using a portable LI 600 stable stomatal. The results indicated that transpiration rate of Thymus serpyllum and Hippophae rhamnoides had no noon expression, was single peak pattern. For Thymus serpyllum, the highest value appeared in 16:00, for Hippophae rhamnoides, from 12:100~16:00, the rate was all higher. However, transpiration rate of Lespedeza davurica, Cleistogenes squarrosa and Astragalia adsurgens cv. were bimodal pattern. The order of mean of transpiration rate in one day is Thymus serpyllumLespedeza davuricaHippophae rhamnoidesCleistogenes squarrosaAstragalia adsurgens cv.. In condition, weather was dry for continuous three years, and some other reasons, water consumption by transpiration of Astragalia adsurgens cv. artificial grassland was biggest, was 7 570.5 g/m 2,Thymus serpyllum community was middle,is 2 071.4 g/m 2, Hippophae rhamnoides shrub forest land was smallest, was 1 169.8 g/m 2.
