Discussion on Ecological Restoration in Dry-Hot Valley

Dry-hot valley is a special natural landscape in southwest China with extremely fragile ecological environment. The wide range, complex and diverse, as well as slow self-repairing of water-fluctuation zone add to the difficulty of ecological management of dry-hot valley. To clarify the development direction of ecological management of dry-hot valley, we introduce the basic situation of dry-hot valley, and systematically review the research progress of dry-hot valley in terms of soil types, physical and chemical properties, water distribution and vegetation restoration techniques, species selection, as well as water-fluctuation zone management. At present, the ecological management of dry-hot valley is in lack of long-term dynamic monitoring and has insufficient microscopic research as well as simple evaluation indicators for ecological restoration benefits. It is an urgent task to apply advanced technical approaches, rationally select good local plant species, and establish long-term dynamic monitoring and evaluation of the ecological environment system, strengthen the self-repair function of the ecosystem to achieve a more scientific and effective management.
