The paper studied three aspects of extracelluar enzymes in sediments of the tidal flat wetland, namely 1 ) the distibution of five sorts of extracellular enzymes in sediments in the east end of chongming island along the elevation gradient or community succession series, the relationships between the activities of enzymes and the ecological factors, and functions of extracellular enzymes in the process of community succession ; 2 ) the effects of the heavy metal ions and edta on the activity of alkaline phosphatase in sediments of the east end of chongming island by adding and removing of heavy metal ions, discussing whether the activities of extracellular enzymes could be taken as the indicators for the environmental status ; 3 ) the variations of the activities of extracellular enzymes in sediments in the east end of hengsha island after the discarding clay
本文以長江口典型濕地?崇明東灘為例，首次研究了沿高程梯度或沿植被演替系列沉積物中堿性磷酸酶等五種胞外酶活性的空間分佈規律，分析了胞外酶活性與環境因子的相互關系及其產生機制，討論了胞外酶活性在濕地植被演替中的作用。同時以崇明東灘沉積物為對象，運用重金屬離子的添加和去除等方法，研究了重金屬離子對沉積物中堿性磷酸酶活性的影響，利用胞外酶活性的變化探討了崇明東灘重金屬污染的狀況。此外，本文還研究了橫沙東灘吹泥試驗工程對沉積物環境因子和胞外酶活性的影響並進行了對比分析。 -
After analyzing, the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak, that is, it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn, salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period
分析得到了潮灘水動力基本特徵：光灘水位漲潮和落潮時間基本相等，而鹽沼前緣帶水位漲潮時間略短；光灘流速過程線在漲潮初和落潮末出現峰值，呈現「雙峰型」特徵，鹽沼前緣帶則冬、春季節呈現「雙峰型」 ，夏、秋季節落潮峰值消失，鹽沼帶四季呈現單峰特徵，潮溝內過程線為「雙峰型」 ；各測點流向均呈現回轉流特徵，在高水位時流向迅速改變，不存在明顯的憩流。 -
