Abstract:

Pioneer plants are the first plants appearing in the community succession, which are of great significance to the development of the ecosystem. In order to give full play to the role of pioneer plants in the ecological restoration of saline-alkali land, this article systematically analyses the ecological value of pioneer plants and conducts in-depth discussions in combination with typical restoration cases. At the same time, specific measures and policy recommendations are put forward for the protection and application of pioneer plants. The research shows that pioneer plants have various ecological values such as improving saline soil, increasing soil fertility, improving soil structure, promoting community succession, etc. They can be used to comprehensively treat saline and alkaline land by selecting and breeding suitable salt-tolerant varieties and combining them with physicochemical methods. Therefore, the study of the ecological value and application of pioneer plants is an important inspiration and experience for the comprehensive management of saline and alkaline land, the effective protection of arable land, and the restoration of ecologically damaged areas.
