摘　　要：在进行一个地区的水资源承载力综合评价时,因影响因素较多,往往会对最终评价结果往往受到较大影响。鉴于此,以江西省水资源的实际情况为例,选取了降雨量、水资源利用率、灌溉率等7个评价指标,应用遗传投影寻踪模型对江西省水资源承载能力进行评价研究。评价结果表明各地区水资源承载力尚有较大的潜力,影响水资源承载力的主要因素是水资源利用率、万元GDP用水量、灌溉率等指标,而缺水率和生态用水率影响较小。Plenty of influencing factors will affect the results of the final evaluation greatly when conducting a comprehensive evaluation on regional water resources bearing capacity. In view of this, by taking the actual situation of water resources in Jiangxi Province as an example, seven evaluating indicators are selected, including rainfall amount, water use efficiency, irrigation rate et al, to evaluate the bearing capacity of water resources with genetic projection pursuit model. The result shows that there is the great potential for the regional water bearing capacity. The indicators such as the water use efficiency, water consumption per 10 thousand yuan and irrigation rate influence the water resources bearing capacity the most, while the water shortage rate and ecological water consumption rate had less influence.
