Soil water content was measured at 28 points in the catchment. biomass and productivity of the plant communities, transpiration rates of dominant plants, and plant community diversity were also measured at various points along the slope. l. in general, it seemed that soil water content increased from the top to the bottom of the catchment.,
在相似植被及坡面形狀條件下，土壤水分沿坡面向上逐漸降低；植被類型及其分佈與土壤水分的坡面分佈密切相關，對上述趨勢有減弱的作用，研究發現在偏旱的2002年生長季末，陰坡灌叢坡面坡下的土壤水分含量明顯低於坡上。 -
In order to maintain the sustainable use of land and water resource, to protect the land from desertification and to make longyangxia reservoir safe, firstly, the spatially disturbed model has been established in which includes dem - based precipitation and runoff, regional transpiration and regional water balance modules in gonghe. secondly, the model of grassland climate potential productivity and the model of grassland productivity modified by plant water demand and stocking intensity factors has been constructed in gonghe. according to the carrying capacity and the actual amount of animals on the grassland, coupled with actual grassland investigation, and by using social - economic data, the grassland productivity, species composition, biotope and the cause of desertification has been analyzed
為了做到對本區的水土資源的可持續利用、防治本區的荒漠化和保護龍羊峽水庫，所以基於dem和已有的氣象、水文長短期觀測和實測數據，首先構建了青海共和盆地降雨、徑流、蒸散和區域水分平衡的分散式模型；進一步在此基礎上，構建了青海共和盆地草地生產力的模型和基於作物水分耗散與放牧因子校正的青海共和盆地草地生產力模型；利用草地載畜能力和現有牲畜量以及社會經濟因子等統計數據，結合實地調查，分析了青海共和盆地草地生產力、物種構成、生境變化和荒漠化成因及其內在驅動因子，並對草地可持續利用做了評價。
