| 摘 要： | 进行脆弱生态环境研究,对生态环境建设与保护具有重大意义。本研究以江西省为例,在G IS支持下,通过构建脆弱生态环境评价指标体系,计算生态环境脆弱度,利用重心迁移模型计算脆弱度等级的重心迁移方向和距离。研究结果表明,自20世纪80年代中期至2000年,该省生态环境总体上有了极大改善,2000年轻度脆弱等级面积122 649.29 km2,占全省总面积的73.5%,比20世纪80年代中期增加919 26.80 km2,增加259.91%;轻度脆弱等级重心迁移结果表明,赣南部生态环境的改善好于赣北部。 |

| Abstract: | There are many types of fragile ecological environments with fast evolvement in many regions in China.The limiting factors of these fragile ecological environments have brought about many obstacles to sustainable development in these regions in the 21st century.The assessment of fragile degrees of fragile ecological environment is important to sustainable development in these regions and in other regions as well.Based on the technologies of GIS and remote sensing,these papers set up an evaluating index system,calculate fragile degrees of fragile ecological environment and analyze the change of fragile degrees use gravity center model. |
| Keywords: | Fragile ecological environment Spatio-temporal evaluation GIS Jiangxi province |
