In this study,the ways of investigating in outdoor typical field and analysis in laboratory were used,and the traditional statistics and geostatistics were used to analysis and treat the data,the variogram analysis of geostatistical and Kriging estimation method were used to study the soil nutrition spatial variances of degraded Seriphidium desert grassland,the main results are as follows:1.

Soil nutrient changes of Seriphidium transillense desert grassland under different degraded degrees;

Seriphidium transiliense desert grassland belongs to the climatic type desert of Central Asia, and distributed only in Xinjiang, the western region of China.

Benefit monitor of retrieving grassland from grazing by remote sensing in natural grassland of Gansu province——Taking the desert grassland of Anxi county as an example;

Study on the oversowing in desert grassland in Tsaidam Basin by hole seeding;

Water characteristics of plant diversity in temperate desert grassland;
