This paper expounds the characteristics of eco-landscapes in hydropower construction region, which is compartmentalized as core disturbance zone, transitional zone and radiated zone according to the degree of construction disturbance. The importance of corridor to eco-landscapes in hydropower construction region is analyzed. It puts forward the principles, modes, steps and measures of building ecological corridor in order to strengthen the bond of isolated patches and between core disturbance zone and surround natural environment, as well as to optimize the ecosystem structure and promote the eco-landscapes in hydropower construction region. Taking the construction region of Xiangjiaba Hydropower Station as an example, through reasonable measures to build corridor network system, the fragmentation of eco-landscapes has been obviously improved, and the core disturbance zone and the peripheral area join to a whole ecosystem. |
