Analysis on Carrying Capacity of Groundwater Resources in Semi-Arid Areas of Western Parts in Heilongjiang Province Based on Matter-Element Model

This paper establishes evaluation model of carrying capacity of regional groundwater resources by method of matter-element analysis, and by this method, it carries on the comprehensive evaluation to carrying capacity of regional groundwater resources in Gannan. According to the evaluation result, carrying capacity of groundwater resources in Ganna test area belongs to the degree of I, which means the groundwater resources still have superior carrying capacity and have great potential to be developed, which provides scientific basis for development and use of regional groundwater resources. This model provides a simpler method for the evaluation in this field.
