- 摘要:
- 针对现阶段县南沟流域因资源利用率低导致的农业产业-资源系统运行相悖等问题，在清洁发展机制（CDM）以及国家生态文明建设理念、生态适宜性评价的基础上，按照县南沟流域可能发展路径（3种模式，7种情景）进行了系统优化。结果表明：农业产业-资源系统优化后，经济效益得到了不同程度的提高。其中在碳汇产业发展模式和生态经济系统优化耦合发展模式的6种情景即碳汇产业融入系统后，生产要素配置发生了重要改变，经济效益得到了显著提升；随着城市化、人类对美好和健康生活需求的提升，建立在特色、低碳、高产、高效下的农业产业-资源耦合系统将成为发展的趋势；相比较而言，现状发展模式优化的结果，导致生态林面积大幅度减少，不符合相关政策确定的方向，因而仅仅是理论上分析的结果。
- Abstract:
- The agricultural resources of Xiannangou watershed were not used efficiently, the system of agricultural industry practices grows inconsistently with agricultural resources. To deal with these problems, three patterns and seven scenarios of the possible development paths of the agricultural industry-resource system were made. On the basis of clean development mechanism (CDM), country’s ecological civilization in China and the ecological suitability evaluation, the system of Xiannangou watershed was optimized. The results indicated that the economic benefits of each phase increased at various degrees, especially in pattern Ⅱ and Ⅲ, in which carbon sink industry joined the system, the economic benefits of the watershed had been significantly improved, and the configuration of factors of production in the system had also changed significantly. With the improvement of urbanization and civil demand for happiness life, the agricultural industry-resource system will become the development tendency in terms of the features, low carbon, high efficiency and high yield. In comparison to the patternⅠ, it was just a theoretical result and can’t be used in reality because the reduction of the ecological forest area didn’t comply with relevant policies.
