Title: Evaluation on Hydrological-ecological Effects of Plantation in Loess Hilly Area in Zhungeer,Inner Mongolia
Abstract: This paper studied hydrological characteristics of litter and soil water physical properties in mature,young and middle-aged forest of Pinus tabulaeformis and Hippophae rhamnoides stands,Caragana korshiskii stands as well as natural grassland in loess hilly area,with taking slope farmland as ck.The results showed that the maximum water absorption of litter in mature forest of Pinus tabulaeformis was 22.6 t/hm2,which was 5~9 times as much as young and middle-aged forest,2.4~3 times as much as shrubbery,and more than 10 times as much as natural grassland.The maximum water-holding capacity between 0~40 cm soil layer in mature,young and middle-aged forest of Pinus tabulaeformis,Hippophae rhamnoides plantation,Caragana korshiskii plantation,natural grassland and cultivated land was respectively 2 260.05,1 935.6,1 935.6,1 820.1,1 597.65,1 666.05,1 600.2 t/hm2;the maximum water-holding capacity between 0~40 cm soil layer in mature,young and middle-aged forest of Pinus tabulaeformis,Hippophae rhamnoides plantation and natural grassland was respectively 659.85,335.4,35.4,219.9,65.85 t/hm2 higher than that of cultivated land.Thus,some indexes of water conservation function such as soil total porosity,capillary porosity,maximum water-holding capacity of capillary and maximum soil water-holding capacity,Pinus tabulaeformis plantation was better than that of shrubs and natural grassland.
