【摘要】：随着我国对外贸易的持续增长和工业、服务业发展水平的提升,沿海、沿江主要港口周边的临港区域产业聚集现象明显,临港区域的大规模、跨越式发展对所在区域的生态环境承载力提出了较高要求；而临港区域的生态环境需水量是研究其区域水资源、水环境和水生态承载力能否满足区域发展要求的重要指标,亦是研究临港区域建设开发过程中生态环境动态变化情况的重要途径。针对目前国内外尚无对整个临港区域生态环境需水量进行研究的情况,本文在临港区域研究和生态环境需水研究的基础理论上,通过分析临港区域生态环境需水的来源和构成结构,将临港区域生态环境需水分为植被需水、湿地需水和城市需水,归纳总结临港区域生态环境需水的特征,构建适用于临港区域的生态环境需水量计算模型,同时对该生态环境需水模型的各个子模块进行细化。利用3S技术、景观生态学等方法处理遥感影像,获得研究区域景观生态类型变化的时间序列,结合气象资料、土壤水文资料、社会经济数据等进行算例所在临港区域的生态环境需水量研究分析,确定其各类生态环境需水量的消耗水平和年际动态变化情况,最后对研究区域的未来需水趋势进行预测。本文研究结果表明：临港区域生态环境需水强度的类别分异较为明显；城市需水的变化是构成临港区域生态环境需水量变化的最主要动因；本文提出的模型应用于临港区域生态环境需水量的计算合理可行,可从生态环境需水量的视角,为港口及临港区域的规划建设提供决策依据。
[Abstract]:With the continued growth of China's foreign trade and industry, the service industry development level, the coastal port area, along the main ports around the industrial aggregation phenomenon is obvious, the port area of large-scale development of the ecological environment, across the region put forward higher requirements of the bearing capacity; but the ecological environment of the port area is the study of the water requirement regional water resources can meet the requirements of the development of an important indicator of regional ecological carrying capacity of water environment and water, is also an important way to change the ecological environment of the port area construction dynamic development process. Aimed at the research content at home and abroad is on the whole port area for ecological and environmental conditions, based on the theoretical research on water requirement of port the research area and the ecological environment, through the analysis of the source port of eco-environmental water demand and the structure of the port, the regional ecological environment needs Water for water requirement of vegetation, wetland water and city water demand, summarize and summarize the characteristics of the port of eco-environmental water demand, water ecological environment model applicable to the construction of the port area, and refinement of each sub module to the model of water ecological environment. The use of 3S technology, landscape ecology and remote sensing image processing method time sequence, changes of regional landscape ecological types, combined with the meteorological data, soil hydrological data, research and analysis of water environmental social and economic data are examples of the port area, the water demand of various ecological environment consumption levels and interannual changes, finally carries on the forecast to the future research of regional water demand the trend. The results of this study indicate that: the port of eco-environmental water demand intensity category differentiation is obvious; the change of city water demand is a port area students The main reason for the change of the environmental water demand is the calculation of the environmental water demand in the port area, which is reasonable and feasible. It can provide decision-making basis for the planning and construction of the port and port area from the perspective of eco-environmental water demand.
