Analysis on Water Conservation Function of Typical Vegetation of Daqing Mountains in Inner Mongolia

Abstract

Abstract: Based on the measurement of forest and soil of 3 typical types of vegetation of Daqing Mountain in Inner Mongolia, water conservation functions of different forest vegetation were studied and compared. The results showed that the canopy interception of Pinus tabulaeformis is 0.170mm, that of Larix principis-rup prechtii and Betula platyphylla 0.104mm and 0.052mm. Water-holding capacity of Larix principis-rup prechtii's litters is significantly higher than Betula platyphylla's and Pinus tabulaeformis's, water-retaining capacity of Betula platyphylla's soil is greater than Larix principis-rup prechtii's and Pinus tabulaeformis's. Through comprehensive evaluation, water conservation function of Larix principis-rup prechtii is the strongest, then Pinus tabulaeformis and Betula platyphylla is weakest.

Key words: water conservation, forest vegetation, Daqing Mountains
