Abstract:

The arid and semi-arid region in northern China is an important ecological security barrier and a key area of the Silk Road Economic Belt. Arid and semi-arid grassland ecosystem has important ecological and production functions, which profoundly affects the ecological environment and, social and economic development of the area. With the intensification of climate change and anthropogenic activities, the plants and soil in the arid and semi-arid grassland ecosystem have undergone significant changes. The responses of plant-soil to precipitation and ecosystem management measures in arid and semi-arid grassland in northern China were reviewed in this paper. The effects of precipitation increase and decrease, grazing, enclosure and nutrient addition on plant characteristics (diversity, functional traits, productivity, etc.) and soil properties (soil physicochemical properties and soil respiration, etc.) were clarified. The changes of grassland plants and soil under precipitation changes and different management measures in arid and semi-arid areas were described systematically. These understanding can provide reference for rational use of grassland resources, restoration of degraded ecosystems and desertification management. At the same time, it can deepen the understanding of the response of grassland ecosystem to climate change and anthropogenic activities, so as to predict the future evolution trend of grassland ecosystem more reliably, and provide reference materials for accurately assessing the risks faced by ecological construction in northern China. The research of ecosystem stability and multi-functionality in the process of desertification land management should be strengthened in the future.

Key words: precipitation variation, grassland ecosystem, community characteristics, soil organic carbon, ecosystem multi-functionality
