- Abstract:
-
Using 3S technology to evaluate the potential of rainwater resource utilization in the karst region of northern Guangdong Province can provide a reference for the evaluation on regional rainwater resources and provide decision support for the development and use of rainwater resources in the study area. The lithology, soil, topography and vegetation as the indicators were selected. Space quantization of indicators was expressed based on 3S technology with remote sensing data, meteorological data and DEM data. Then the potential of rainwater resource was estimated based on this. The results showed that: (1) the potential of rainwater resources calculated by the three models all showed the characteristics of block distribution and gradient change, and the gradient change gradually increased from model 1 to model 3; (2) spatial distribution of potential of rainwater resources in karst region of northern Guangdong Province was uneven, and the regional difference was great; (3) principal component analysis showed that the potential of rainwater resources utilization was affected by various factors, and lithology and topography had the higher contribution rates to the potential.
