[Land-use strategy in riverine area].
The land near river is one kind of land zone that is inseparably related to the ecological process of river and lake, and directly affected or endangered by flood. Combined with ecological principles and the theory of forest eco-network system in China, the landscape security, the principles and directional thoughts, the theoretical basis and strategy were comprehensively studied in this paper. The landscape security should include three aspects of ecological benefit security, economical benefit security, and social benefit security. The land-use principles should be to find the best uniting section and ensure integration of the three principles together. The directional thoughts should be to combine management and development together, strengthen the landscape security by various measures, and carry out the near natural land-use and managing strategy by increasing the proportion of forest. Different development models should be selected in different rivers and regions. According to the risk grades of flood disturbance and spatial differentiation of lands near river, the different managing strategy with different disturbance degree should be carried out in different reach in upstream, midstream, and downstream based on the spatial differentiation of river and lands nearby in longitudinal direction, while based on the spatial differentiation and security during flood in cross direction, the utilization strategy should be classified and aimed at fragile use zone, stable use zone, and elastic use zone, respectively.
