为分析鄱阳湖流域水源涵养及自然发展下土地利用变化对水涵养的影响,利用生态系统服务和权衡的综合评估(integrated valuation of ecosystem services and trade-offs,InVEST)模型与元胞自动机-马尔可夫(cellular automata-Markov,CA-Ma...为分析鄱阳湖流域水源涵养及自然发展下土地利用变化对水涵养的影响,利用生态系统服务和权衡的综合评估(integrated valuation of ecosystem services and trade-offs,InVEST)模型与元胞自动机-马尔可夫(cellular automata-Markov,CA-Markov)模型分析了鄱阳湖流域2000—2018年的水源涵养状况,并预测分析了2018—2035年的状况。结果表明:1)2000—2018年的鄱阳湖流域水源涵养总量变化与降雨量变化趋势的分布相似,其中2010年水源涵养量最大,2000年水源涵养量最小,从流失结果来看,自2015年后,流失量与降雨量大的变化趋势相反,这说明2015年后该区域的保水能力逐渐变小;2)2018—2035年间,研究区域的预测土地利用演化趋势与2010—2018年的演化趋势相同,区域内建设用地这一径流系数大的用地类型持续扩张,而利于水源涵养的林地逐年减少,2018—2035年间,在降雨不变的情况下,水源涵养逐年降低,流失量逐年增多,且水源涵养低值依旧聚集于冷点区。展开更多
