Grassland industry and ecological security in the Hexi Corridor

Land desertification in the Hexi Corridor has accelerated due to changes in environments and intensification of human activities. This land desertification has threatened local economic development and ecological security of the Eurasian Continental Bridge. Based on the analysis of the Ecosecurity crisis for the Hexi Corridor, this paper indicated that ecological projects of grass industry should be built to prevent land desertification and improve Ecosecurity; and pointed out that the ecological engineering of grass industry mainly included three aspects: Firstly, windbreak and sand fixation ecological protection grass belts along the blown sand lines should be built to protect the existing grassland vegetation. Secondly, grass livestock transformation ecology industrial belts in oasis should be built to adjust planting structure. Finally, farming and animal husbandry complementary ecology displacement belts along the Qilian Mountains should be built to implement the balance between livestock numbers and forage resources.
