The results show that: 1) Wet index, accumulated temperature, isothermal, and annual average temperature range are the four major climatic factors affecting the distribution of perennial cultivated grasses in the Northwest Sichuan Plateau. 2) Model training and prediction data can be achieved well under the appropriate range of major climatic factors. 3) Under the background of climate warming, from now to 2080, the potential distribution of perennial cultivated grasses in the Northwest plateau of Sichuan, China will increase. The study aims to provide scientific decision-making basis for maintaining grassland ecosystem stability and promoting desertification management and even industrial restructuring of agriculture and animal husbandry.展开更多

The results shown that fox prefer to select those habitats, in which, the base diameter of shrub is bet ween 50 cm and 100 cm and the height range is between 30 cm and 50 cm.Furthermore, the slope range is between 20 o and 30 o and the relative altitude range is between 100 m and 200 m.Our researches demonstrated that, for Tibetan fox, the main threat comes from human activity.The local people should pay more care on fox and protect the shrubs i n itDK’s habitat.展开更多
