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。 -
The study covers regional stratigraphy, regional geological structures and their evolution ; deep - large fracture system and building - moutain straps in the basin ; distributing of mineralization concentration area and mineralazition characteristics of different metal fields ; volcanic magmatic activity and magmatic distributing ; the petrology, element geochemistry features of the magmatic rock series ; the relationship between magmatic distributing and mineralization ; the relationship between magmatic forming - age and mineralization ; the relationship between magmatic form and mineralization ; source of mineral materials, source of hydrothermal solution and source of mineralizing agent ; transport forms of metal in the solution ; the ore - forming geochemical mechanism, etc. it turns out as follows : ( 1 ) lanping basin formed in the linkup of the plates and it was propitious to form deep - large fracture
