The Measurement Of The Ecological Benelfits Of Main Vegetation Types In Daqing Mountain

The experiment is located in the ecological forest areas of Hotwater Beam Daqing Mountain,Inner Mongolia. In this paper,the object of studying are the different developmental stages of Pinus tabulaeformis,Birch natural secondary,shrub and grassland slope.The benefits of different vegetation types of wanter conservation and conservation of soil can be measured by the way of natural rainfall and artifical rainfall.In addition,because of the unique geographical location and natural landscape of Daqing mountain,the study area of landscape benefits has measured through the design of questionnaire forms. Key findings:(1)Using of observation data on rainfall and canopy interception,the regression equation of rainfall and canopy closure has been established and estimated canopy interception of the different developmental stages of ptabulaeformis plantations and natural secongdary birch.The total value of water conversation of the diffierent vegetation types are1.6422million yuan、2.18828million yua、811,390yuan、610,400yuan.(2)Under simulate different rainfall intensity,the total valve of loss soil in different developmental stages of pinus tabulaeformis and birch natural secondary forest are61.39-136.37yuan/hm2and8.24-113.37yuan/hm2; the total valve of loss soi in tiger hazelnut shrub and grassland slope are28.11-59.11yuan/hm2and93.92-107.61yuan/hm2.(3)By researching on the landscape resources of ecological forest areas,the environmental factors has been evaluated.Using the methord of travel the landscape value of the eco-forest areas is7.6383million yuan.The willingness to pay ecological forest of visitors has been investigated.
