Ecology effect of retrieving grassland from grazing on desertification grassland vegetation in Anxi;

The content characteristics on Fe, Mn and Cu in the grassland vegetation of Xilin River Basin;

The advance of technology of remote sensing monitoring for grassland vegetation in China, especially administered by the Ministry of Agriculture of China, is reviewed in this paper.

Plant community succession of degradation and desertification in sandy grassland.;

The effect of protecting Artemisia frigida communities on preventing sandy grassland desertification was studied.

Some conclusions are: 1) The areas of degraded grassland in 2005 were bigger than in 2006 in eastern Mongolia,but the whole grassland vegetation growth was better than in 2004;2) In 2005,vegetation growth in desertified grassland of western Inner Mongolia-Ningxia-Gansu was worse than in 2006 and the variance was smaller;3) The share of areas in no.

A study was carried out on the relationship between the changes of micro-relief and the changes of plant communities as well as their spatial distribution patterns,by systematic sampling in a dry depression and its adjacent flat background grassland in the Hulunbuir sandy meadow grassland,Inner Mongolia,China.

The artificial sand-fixing vegetation under no-irrigation condition was establ ished in 1956, which is a successful model of protective system for railway comm unication in China.
