Adverse effects of desertification in Saihanba: the measures for preventing wind and fixing sand in the surrounding areas can't keep up, and the phenomenon of sand dune activation and land desertification appears in some places, which not only causes the erosion of newly reclaimed land by sandstorms, but also intensifies the harm to nature reserves. The development of animal husbandry has caused serious overload of grassland, aggravated grassland degradation and even desertification.

With people's concern about the quality of living environment and their thirst for natural ecology, the construction of nature reserves has attracted more and more public attention. Protected area is a special type of land use, and its main purpose is to protect species, ecosystems or natural heritage. The purpose of establishing nature reserves is not simple passive protection, but rational development and utilization of natural resources under the premise of effective protection, giving full play to the resource advantages and scientific and technological advantages of nature reserves. According to the principle of ecology, we should make rational use of resources to strengthen the construction of nature reserves in order to promote the coordinated development of nature reserves and forest farms. Any forest resource has certain ecological public welfare function. Only by paying equal attention to resource development and protection, cooperating with the strategy of sustainable development, and doing a good job in the management and protection of forest ecological resources can we give full play to the ecological public welfare function of forests.
