在分析生态产业概念的基础上,从半干旱黄土丘陵沟壑区的自然特点出发,分析了区域生态环境及资源环境的特点、优势及不足,分析了影响生态产业发展的主要约束条件。在流域尺度内,提出了适宜发展的三大产业,即旱作农产业、草畜产业和林果产业,分析了产业发展的前景与策略。在建设生态和发展产业的具体实践中,要充分考虑生态与产业的紧密结合,使生态建设融于产业发展之中,在发展产业中实现资源的生态价值和经济价值。 Based on the analysis of the concept of eco-industry and starting from the natural features of semi-arid loess hilly and gully regions, the characteristics, advantages and disadvantages of regional eco-environment and resources and environment were analyzed. The main constraints affecting the development of eco-industries were analyzed. Within the catchment scale, three major industries suitable for development are proposed, namely dry farming, livestock and poultry industry and forestry and fruit industry, and the prospect and strategy of industrial development are analyzed. In the concrete practice of building ecology and developing industries, we must fully consider the close combination of ecology and industry, integrate ecological construction with industrial development, and realize the ecological value and economic value of resources in developing industries.
