| 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. |
