Abstract: | Presently concepts and methods related to water resources conservation of mountain rivers are seriously insufficient, and
its level is far from being adaptable to the development of a harmonious society. As mountain ecosystems play a key role in
water resources conservation of mountain rivers, and the characteristics of mountain ecosystems and hydrologic features of
mountain river follow strong temporal and spatial distribution, partition theory can be applied to the water resources conservation
of mountain river. This theory observes the following partition principles: regional relativity, spatial continuity, integralcounty,
meeting management needs, hierarchical principle, and comparability principle. And it lays equal emphasis on both water resources
conservation and environmental protection, on both water quality conservation and water quantity protection, on the combination
of water features, water cycle and water pollution. In the partition methods, index method and map superposition method will
be applied in region partition. The example of region partition of water resources conservation in the upper reaches of the
Yangtze River shows that the partition theory is practicable in water resources conservation of mountain rivers, and it provides
a platform for future study in water resources conservation. |
