This study evaluated changes in wetland components,spatial pattern and hydro-ecological function of the typical wetlands on the Qinghai-Tibet Plateau on the basis of three sets of remote sensing data (1969,1986 and 2000) and field investigations.

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.

Evaluation and protection measures of ecological functions of Baiyangdian Lake marsh;

Herbivore-induced plant volatiles: from induction to ecological functions;

Contributions of soil micro-fauna (protozoa and nematodes) to rhizosphere ecological functions;

Evaluation of soil conservation eco-function and eco-value of the Ebinur Lake Wetland Natural Reserve District in Xinjiang;

Using "3S" technology and map overlay method,nodal region of Ebinur Lake basin could be ecological characterized 4 eco-function region and 9 sub-eco-function with top-down way.

It was the first time to put forward the "gene" technique or "material chip" technique of manufacturing function micro-aggregates and eco-function elementary materials.
