[0002] In alpine regions, especially in the vast western region, the annual precipitation is low, which leads to a serious water shortage problem in the growth process of plants. Even in the relatively abundant precipitation of winter and summer, due to the frost at night, the plants may also produce physiological water shortage, which further aggravates the pressure of water supply. The temperature in alpine regions is low, and it is cold in winter and cool in summer, which seriously limits the growth of plants, and due to the cold climate, the soil may remain frozen for a long time, affecting the growth and development of plant roots, thereby limiting the absorption of water and nutrients by plants. Therefore, constructing water and heat supply conditions for vegetation growth in alpine regions is the key to solving the problems of slow vegetation, low vegetation coverage, and land desertification in alpine regions.
