Abstract
The Hotan Region in xinjiang, China is a typical arid area. Natural factors determine that the ecological stability of the area is poor, easy to be damaged and difficult to recover. In order to improve the local ecological environment, this study explored an ecology restoration model with the artificial Tamarix-Cistanche. After the long-term monitoring and comparison at four test sites, it was found that this model also increased the per capita income, reduced the poverty in local farmers, and solved the problem of no direct economic benefit from foresting, as well as the following ecological benefits (1) improving the soil properties, and increasing its powder content and fertility, (2) improving the regional microclimate, reducing the daily temperature and relative humidity ranges, and reducing the regional wind speed, (3) restoring the biodiversity, increasing the vegetation coverage and the amount of animals and plants, and enhancing the water and fertility retention of the soil.
Highlights
The Hotan Region in xinjiang, China is a typical arid area
The mechanical composition of all soil samples was determined. It can be found from the results (Table 1) that the powder contents at different depths of the topsoil taken from the four test sites were significantly higher than those from the control sites
The soil organic matter, organic carbon, total N, total P, total K and other chemical components were determined. It can be found from the results (Table 2) that these parameters of the soil layers of the four test sites were higher than those of the control sites
Summary
The Hotan Region in xinjiang, China is a typical arid area. It is the natural factors that result in its reduced amount of living beings, simple ecological structure, poor stability, vulnerability, difficulty in restoration and other fragile characteristics (Fang et al 2001; Zhang et al 2011). Cistanche is a valuable herb in traditional Chinese medicine. It is widely used in Chinese medicine and health care non-prescriptively due to is benefits of enhancing the immunity and promoting metabolism. As a promising business, the Artificial Tamarix-Cistanche model will both improve the living conditions of local farmers and restore the desert ecological environment. On the basis of fully understanding the importance of ecology restoration, this paper explored the ecology restoration model with the Artificial Tamarix-Cistanche, scientifically analyzed and assessed the ecological benefits for Hotan after its implementation, provided important theoretical basis for the promotion and application of ecology restoration project, and played a practical role in promoting the sustainable development of the local agriculture and forestry
