Abstract:

In recent years, due to the dual impact of climate change and human activities, ecosystems have been suffering increasing pressure. To a certain extent, this pressure has changed the structure and process of ecosystems, reduced ecosystem services, and threatened regional sustainable development. Land ecological restoration is a major measure to promote the construction of ecological civilization and an important means to deal with the above ecosystem problems. China has taken it as one of national strategies. However, there have been relatively few systematic reviews and summaries in the current research on the ecological restoration of land and space, which is not conducive to the in-depth development of ecological restoration. Therefore, this article systematically sorts out the evolutionary context of China's ecological restoration work, expounds the differences in the goals, methods, and regions of land and space ecological restoration in different periods, analyzes the current problems encountered in China's land ecological restoration work, and further proposes related countermeasures, which are expected to benefit China's ecological restoration work in the new era. The research shows that: (1) China's ecological restoration research has experienced an evolutionary process of budding, early practice and the new era periods. The ecological restoration goals, methods and regions differed significantly in each period. (2) At present, the main problems of China's territorial and spatial ecological restoration are that there are many historical debts in ecological aspects, many practical contradictions, problems of ecosystem functions are more prominent, the responsibilities of ecological restoration departments are relatively scattered, and the performance of duties is relatively contradictory and single. (3) In the future, targeted land ecological restoration work should be carried out based on the differences in the time dimension, space dimension, administration and market dimension of ecological problems.

Key words: land ecological restoration, ecosystem problems, differentiation, countermeasures
