在全面分析黄土丘陵沟壑区生态-经济敏感带的自然环境、社会经济环境的基础上,深入探讨了区域的优势景观单元——小流域的景观结构和功能,由此提出了构建小流域生态——生产范式的几项原则及范式内容。其中包括以下几项原则:水分平衡和高效利用原则、农林牧复合系统原则、区位优化原则等。范式内容强调小流域景观单元的空间异质性和等级特点,主要包括以村庄为中心的高效农业生产圈层结构模式、坡面梯状生态经济带建设模式、流域生态-经济水平生产模式、流域之间高效能流物流点-轴发展模式以及流域与外界环境的核心-边缘发展模式。
On the basis of comprehensively analyzing the natural environment and socio-economic environment of the ecologically-economically sensitive belt in the loess hilly and gully regions, this paper discusses in depth the landscape structure and function of the small watershed, the dominant landscape unit in the region, - Several principles of production paradigm and paradigm content. These include the following principles: the principle of water balance and efficient utilization, the system of agroforestry system and the principle of location optimization. The content of the paradigm emphasizes the spatial heterogeneity and grade characteristics of landscape units in small watersheds, including the village-centered structure model of high-efficiency agricultural production, the construction mode of slope-shaped ecologically-oriented economic belts, the eco-economic production pattern of watersheds, Between high-performance logistics point-axis development model and the core of the basin and the external environment - the marginal mode of development.
