由于人口密度增大,人类活动强度增加,西藏—江两河地区荒漠化的进程在不断加快,沙地面积在不断扩大。该区域控制荒漠化的主要途径是:保护自然植被、改变向荒山要粮的传统思路和强化对沙化石质化低质草地的改造。据此本项研究提出了该地区荒漠化控制措施是:进行农业景观结构调整,不提倡开荒要粮,而是以推广农业新技术为主的方法提高现有农田单产水平;用封育和恢复植被相结合的方法改造沙化石质化低质草场;推广以能源改造为中心的新技术。这样才能有效地遏止荒漠化进程。
Due to the increase in population density and the increase in human activities, the process of desertification in the Tibet-Jiangshuhe region has been accelerating and the area of sandy land is constantly expanding. The main ways to control desertification in this region are: protecting natural vegetation, changing the traditional thinking of supplying grain to barren hills, and strengthening the transformation of desertified sandy grasslands. Based on this, the research proposed that the desertification control measures in this area are as follows: to adjust the agricultural landscape structure, not to promote land reclamation and grain, but to promote the new agricultural technology as the main method to improve the existing farmland yield; with the sealing and restoration of vegetation A combination of methods to reform the desertification of low-quality grassland; promotion of energy-based transformation of new technologies. Only in this way can we effectively stop the process of desertification.
