Effects of Grain-for-Green on Soil Quality in Huangshui River Basin of Qinghai Province
摘要
Abstract
Based on sample collection,field monitoring,and indoor experiments,the effects of different types of Grain-for-Green on soil quality were investigated in Huangshui drainage area of Qinghai Province.The results of sample analysis indicate the forests with the same age（8 a） in the order of decreasing soil organic matters,total porosity,and total amount of microorganism as： mixture of Picea crassifolia and birchbirchmixture of Picea crassifolia and Hippophae rhamnoidesPicea crassifoliaHippophae rhamnoidesfarmland;in order of decreasing soil bulk density and pH value as： mixture of picea crassifolia and birchbirchmixture of Picea crassifolia and Hippophae rhamnoidesPicea crassifoliaHippophae rhamnoidesfarmland;in the order of decreasing water holding capacity as： mixture of Picea crassifolia and birchHippophae rhamnoidesbirchPicea crassifoliafarmland;in the order of decreasing erosion resistance（K） as： Hippophae rhamnoidesmixture of Picea crassifolia and birchmixture of Picea crassifolia and Hippophae rhamnoidesbirchPicea crassifoliafarmland;and in the order of decreasing heat capacity as： mixture of Picea crassifolia and birchbirchmixture of Picea crassifolia and Hippophae rhamnoidesHippophae rhamnoidesPicea crassifoliafarmland.The results also show soil microorganisms in the order of decreasing total amount as： bacteriaactinomycetes epiphyte.Specifically,bacteria accounted for over 95 percent of the total microorganism.关键词
