| 摘要: |
| 随着城市化发展和人口增长,济南岩溶地下水位下降、泉水流量衰减、岩溶泉域生态环境脆弱等问题凸显。本文在分析济南市岩溶泉域水文地质特征、岩溶补给区与重点渗漏带变化的基础上,综合运用3S技术,特别是RS的多源遥感数据,解译了近四十年区域土地利用与植被覆盖度,定量分析了区域植被覆盖度与土地利用类型的变化特点,揭示了济南市岩溶泉水补给区植被演变的规律和特征,是区域生态环境系统研究新的尝试和探索,其研究成果为济南市岩溶泉水补给区生态环境保护与重建、资源可持续利用决策提供科学依据。 |

| Abstract: |
| The problems such as the reduction of the karst groundwater level, the attenuation of spring, the fragility of ecological environment are more serious With urbanization and population growth in Jinan spring area. Based on the analysis of Jinan karat hydrogeology and the change of recharge area and the major leakage area, Applying 3s technology especially RS multi-source remote sensing data, Deciphering the regional land use and vegetation coverage about 40 years, quantitative analysis of the regional vegetation coverage and the change characteristics of land use types, reveals the Jinan karst spring water recharge area regularity and characteristics of ecological environment evolution, is the new attempt and exploration region Vegetation evolution system research, the research results for the Jinan karst spring recharge area ecological environment protection and reconstruction, the sustainable development of resources decision-making provide a scientific basis. |
