沙 The ecological construction of seabuckthorn in the sandstone area has effectively controlled the 砒 sandstone areas known as “environmental cancers”, and the forest coverage rate has been increased from 10% to 35.3%. Each year, it can contain 4.9 million m3 of runoff and intercept silt sand 200 10,000 t effectively control soil and water loss, prevent desertification of the soil, and significantly improve the ecological environment. The productivity of the land is increased from 15 5 4 yuan / hm 2 to 769 8 yuan / hm 2, basically achieving the coordination of environmental benefits and economic benefits. sustainable development. The experience and practice of seabuckthorn ecological construction in Zhunge’er flag was introduced
