【摘要】：流域生態(tài)系統(tǒng)產(chǎn)水服務(wù)功能的空間化和定量化評估,對流域水資源管理、優(yōu)化配置以及提高流域水生態(tài)保護(hù)效率具有重要意義。以山東省南四湖流域為研究對象,基于1990—2013年土地利用、降水、蒸散以及土壤屬性等基礎(chǔ)地理數(shù)據(jù),以InVEST模型為基礎(chǔ),評估和模擬南四湖流域近25 a的產(chǎn)水量,并采用ArcGIS分析產(chǎn)水量的空間分布格局以及變化趨勢,探討了降水、地形等自然地理要素以及人口、土地利用和國內(nèi)生產(chǎn)總值(GDP)等社會經(jīng)濟(jì)因素與產(chǎn)水量空間格局動態(tài)變化之間的關(guān)系,并在此基礎(chǔ)上劃分出南四湖流域生態(tài)系統(tǒng)產(chǎn)水功能區(qū)。研究結(jié)果表明:流域產(chǎn)水量在空間格局上呈現(xiàn)出由東向西遞減的趨勢,東部、東北部等山區(qū)、丘陵地區(qū)產(chǎn)水量高,西部平原地區(qū)產(chǎn)水相對較低;受自然地理要素影響,流域產(chǎn)水量空間分布與社會經(jīng)濟(jì)發(fā)展水平即GDP、人口密度的空間分布格局有較大差異。近25 a來,流域產(chǎn)水量呈現(xiàn)減少趨勢,且產(chǎn)水量峰值區(qū)域由東北部向偏南地區(qū)轉(zhuǎn)移,最低值區(qū)由西部向中部地區(qū)轉(zhuǎn)移。降水、海拔和坡度等地理環(huán)境與產(chǎn)水量的空間變化呈顯著正相關(guān),其中降水量的相關(guān)程度最強;人口、GDP等社會經(jīng)濟(jì)數(shù)據(jù)與產(chǎn)水量變化也呈顯著正相關(guān),主要原因在于城市化的發(fā)展,城市建設(shè)用地等不透水層增加,促進(jìn)了流域產(chǎn)水量。研究結(jié)果可以為流域水資源政策制定以及社會經(jīng)濟(jì)發(fā)展規(guī)劃等宏觀決策提供科學(xué)支撐。
[Abstract]:The spatial and quantitative evaluation of the water supply service function of the watershed ecosystem is of great significance to the management of water resources in the basin, the optimal allocation and the improvement of the efficiency of water ecological protection in the river basin. Based on the land use, precipitation, evapotranspiration and soil properties of the Nansi Lake Basin in Shandong province from 1990 to 2013, the basic geographic data, such as the land use, precipitation, evapotranspiration and soil properties, are based on InVES Based on the T model, the water yield of nearly 25 A in the Nansi Lake Basin was evaluated and simulated, and the spatial distribution pattern and change trend of the water yield were analyzed by ArcGIS. The dynamic changes of the social and economic factors such as the precipitation, the topography and other social and economic factors such as the land use and the gross domestic product (GDP) and the spatial pattern of water production were discussed. The results show that the water yield of the river basin shows a trend of decreasing from east to West in the spatial pattern, in the East, in the northeast, in the hilly area, and in the western plain area, the water yield is relatively low in the western plain area, and the water yield of the river basin is influenced by the natural geographical factors. The spatial distribution of the spatial distribution and the social and economic development level is GDP, the spatial distribution pattern of population density is very different. In the near 25 A, the water yield of the basin shows a decreasing trend, and the peak area of water yield is transferred from the northeast to the south, and the minimum area is transferred from the west to the central region. The change also showed significant positive correlation, among which the correlation of precipitation was the strongest, and the social economic data such as population and GDP were also positively correlated with the change of water production. The main reason was the development of urbanization, the increase of the urban construction land and other impermeable layers, which promoted the drainage of water resources in the basin and the social economy. Macro decisions, such as the economic development plan, provide scientific support.
