基于脆弱性和可持续生计视角的黄土高原生态环境治理研究
- Title:
- Eco-environmental Construction on the Loess Plateau Based on the Perspective of the Vulnerability and Sustainable Livelihoods Approaches
- Keywords:
- Loess Plateau; eco-environment; vulnerability; sustainable livelihoods
- 分类号:
- X171.1;F323.2
- 摘要:
- 脆弱性和可持续生计在国际上倍受关注，脆弱性分析和可持续生计方法已经成为可持续发展研究的重要工具，该文以脆弱性和可持续生计为视角，对黄土高原现行的水土流失治理和生态环境建设的模式进行审视，认为坝系退耕、赈济退耕、梯田退耕、集雨工程、生态移民5种模式的实质是通过人为干预改变黄土高原水沙运移的时空特征，遏止日趋严重的水土流失，防止生态环境进一步恶化，实现黄河中下游的生态安全和可持续发展；不同模式在黄土高原水土流失治理和生态环境建设中各有其优势，也各有其脆弱性，其应用和推广必须因地制宜，必须适应黄土高原的自然地理分异特点，必须考虑地方居民的可持续生计，不能以偏概全，要统筹考虑。
- Abstract:
- In recent years, the vulnerability and sustainable livelihoods approaches have been the most important topics in the fields of sustainable sciences. This paper researches on the water and soil erosion modes and the eco-environmental construction with the concept of vulnerability and the sustainable livelihoods approaches, and analyzes the characteristics of the five kinds of ecological de-farming modes: the dams de-farming, the relieve de-farming, the ladder de-farming, the rain water harvesting project and the ecological migration, and argues that the essence of all kinds of ecological de-farming modes exists in changing the spatial and temporal characteristics of water and soil on the Loess Plateau, to control the water loss and soil erosion, to protect eco-environment from steady deterioration, and to achieve the ecological security and sustainable development in the of the middle and of the lower reaches of the Yellow River. Different ecological de-farming mode has advantages and disadvantages respectively, and the vulnerability is different too, thus the applications of them have to take the rule of territorial differentiation and sustainable livelihoods of the local people into consideration in the mean time, have to take the whole situation into account.
