The ecohydrological functions of litter were studied,which include litter storage,annual litterfall and dynamics,water holding capacity,interception effect on rainfall,restraining effect on soil water evaporation,and retarding effect on runoff.

Freezing-thawing rule of seasonal frozen soil and its eco-hydrological function in Zhalong Wetland;

To study the eco-hydrological function of litter and soil, a natural mixed forest of oak(Quercus liaotungensis) and linden(Tilia paucicostata) and a plantation of larch(Larix principis-rupprechtii) in the small watershed of Xiangshuihe in south side of Liupan Mountains of Ningxia Hui Autonomous Region were selected as research stands.

Person and natural ecological relationships constituted by person s survival relationships should become the foundation and the premise to construct the ecological literary arts research object.
