| 摘 要： | 为定量研究水土流失对区域生态安全的影响,以江西省为研究对象,基于水土流失状况,构建江西省生态安全评价指标体系,利用压力-状态-响应模型对江西省生态安全进行评价。结果表明:1)从1996到2000年,江西省生态安全水平好转,但全省整体生态安全水平只有Ⅱ级,生态安全压力仍然很大;2)江西省生态安全水平区域差异明显,主要表现在空间分布格局和绝对数值差异上;3)江西省水土流失与生态安全关系密切,随着整体生态安全水平的提高,水土流失对生态安全影响越来越大。

| Abstract: | In order to study the influences of soil erosion and water loss to ecological security of Jiangxi Province,the ecological security assessment system indices of Jiangxi Province indices was constructed based on soil erosion and water loss.Then,provincial ecological security assessment was curried out using pressurestate-response model.The results showed that: 1) Ecological security level of Jiangxi Province took a turn for the better in period from 1996 to 2000.However,the provincial integer level of ecologi... |
