A Study of Water Conservation Capacity and Value Evaluation of 9 Kinds of Typical Vegetation Community in the Zagunao River of the Minjiang River

Litter and soil water-holding capacity is one of the important components of computing function of water conservation vegetation community.In this paper,Cupressus chengiana forest,Robinia pseudoacacia forest,Pinus tabulaeformis forest,Cotinus coggygria forest,Populous and Salix forest,Picea and Abies forest,Quercus aquifolioides forest,Rosa brush and Hippophae rhamnoides brush were taken as the research objects,the litter and soil water-holding capacity in 0~40 cm were evaluated and calculated.The results showed that the total litter water-holding capacity of 9 plant communities was about 27 099 t.The total soil water-holding capacity in 0~40 cm of 9 plant communities was about 331 751 t.Based on the 686.8 hm² plant communities in Xionger village,the total water-holding capacity of litter and soil in 0~40 cm was about 358 850 t,and the total water conservation value was about 2.193 million Yuan.
