Investigation report on soil salinization around Aral Sea

According to the schedule of the project implementation plan and commissioned by the project team management committee, the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences organized a team of 6 people to carry out a field investigation in the Aral Sea from November 15 to November 26 in view of the desertification, salinization and vegetation construction of the surrounding land. The history, current situation, harnessing work, achievements and pressing problems of soil desertification and salinization around the Aral Sea were preliminarily understood. Sampling of vegetation and soil was carried out, and the technical idea to solve the problem was put forward, that is, planting Halophytes in brackish and saline groundwater to realize rapid vegetation construction in saline-alkali land. Through on-the-spot investigation, the investigation group believed that the implementation of vegetation construction in saline-alkali land should mainly focus on halophytes and local tree species. According to the distribution law of local halophytes and the characteristics of main constructive species in saline-alkali land, combined with the climatic conditions of the implementation site, seven halophytes, such as Salt-eared Tree, should be selected for planting demonstration. After the investigation, the investigation group put forward three specific suggestions on vegetation construction in saline-alkali land.
