Abstract: |
A system of candidate indices, including 4 classes and 15 factors, was set based on the basic data collected from Liao River Basin of Liaoning province in 1980-2005. Principal component analysis, entropy methods and correlation analysis were used to evaluate the function. The results showed that production function was stronger than habitat function, information function and regulation function, which would provide useful information and foundation for functional division, reasonable use of water and economic development.
