摘 要:小流域的横向地貌结构、纵向地貌组合以及地面坡度组成,共同决定了流域内生态环境的分异,制约着流域内农业生产结构和生产布局.充分发挥流域自然生产潜力,需要根据地貌结构,建成农、林、牧、副、渔综合发展的复合生态经济系统.The differentiation of ecological environments in watershed was decided by geomorphic cross-section structure,geomorphic longitudinal combination and ground slope composition in small watershed. They also restrict agriculture production structure and allocation. According to geomorphic structure,need to complete a compounding ecological and economic system in order to bring the nature production potential of watershed into full play, where agriculture, forestry, animal husbandry, sideline and fishery is developed in a comprehensive way.
