为了探讨城市化进程对上海市浦东新区河网水系的影响,从河网水系结构和功能特性出发,选取河流水面面积、数量、连通性等指标,分析了河网水系演变特征及其对城市化过程的响应规律。研究结果表明：受快速城市化过程影响,2000~2010年浦东新区的河网水系发生了较大的变化,河流长度和面积均明显下降、斑块数明显增加；从各指标的变化趋势来看,2000年河网水系连通性、面积、破碎度等指标最好；2010年仅水质指标表现为最好,其他指标均表现为最差。研究成果为该区域的水系保护与修复提供了依据。
為瞭探討城市化進程對上海市浦東新區河網水繫的影響,從河網水繫結構和功能特性齣髮,選取河流水麵麵積、數量、連通性等指標,分析瞭河網水繫縯變特徵及其對城市化過程的響應規律。研究結果錶明：受快速城市化過程影響,2000~2010年浦東新區的河網水繫髮生瞭較大的變化,河流長度和麵積均明顯下降、斑塊數明顯增加；從各指標的變化趨勢來看,2000年河網水繫連通性、麵積、破碎度等指標最好；2010年僅水質指標錶現為最好,其他指標均錶現為最差。研究成果為該區域的水繫保護與脩複提供瞭依據。

In order to analyze the impact of urbanization on river network of Pudong New Zone of Shanghai City, from the as-pects of river network system structure and function, the river network evolution characteristics and its response to the urbaniza-tion process are studied by indices of river area, river quantity, river-system connectivity etc. The results showed that affected by the rapid urbanization, great changes occurred in river network of Pudong New Zone from 2000 to 2010;river length and area decreased significantly while the river patches increased;in the view of index variation trend, the river system connectivity, river area, fragmentation were the best in 2000;in 2010, the water quality index was the best and other indices were the worst. The research results provided the basis for water system protection and restoration in this region.
