A regional environmental management information system for Chinese EPA—the system analysis and design

REMIS is one of key research projects sponsored by the central government. It is recommended to regional EPAs as a main tool of the environmental management. REMIS simulates the functions of the regional EPAs and aimed to improve their management level. The national environmental management information system will base on REMIS.Functional analysis is the kernel of the REMIS system analysis. Data and data flow analysis are used to support the functional analysis.Investigations on the functions of the local EPAs of eight provinces and 12 cities have been taken. The functions were carefully sorted. Modular design method was used in system analysis and system design.The system analysis included functional analysis, data analysis and data flow analysis. The system design is based on the system analysis. HIPO diagram of each modular, data base structure, menu design, selection of hardware and software environment were the main items of the system design.

烃类化合物气相色谱保留指数与其分配系数关系研究

报道了从烃类化合物气相色谱保留指数预测其正辛醇水分配系数的公式，研究了以不同极性相上测得的烃类化合物保留指数预测其分配系数的准确性，得出弱极性柱上测得的化合物保留指数能更准确的预测其分配系数，从而为烃类化合物分配系数的测定和预测提供了一种简便易行的新方法。     

云南白秧坪铜银矿床Cu、Ag迁移形式探讨

在野外地质研究的基础上,采用地球化学热力学方法研究了Cu、Ag的迁移形式。研究结果表明,铜在热液中主要以CuCl42-、Cu(H2O)42+、Cu(S2O3)46-、CuS46-、Cu(HS)42-、Cu(SbS3)410-形式迁移;银在热液中主要以AgCl2-、Ag(S2O3)23-、Ag(HS)2-、AgS23-、Ag(SbS3)25-形式迁移。铜银矿床是在含矿热液物理化学条件发生改变的情况下铜银化合物发生解析作用而成。

Analysis on sensitivit and landscape ecological spatial structure of site resources

This article establishes a set of indicators and standards for landscape ecological sensitivity analysis of site resources by using the theories and approaches of landscape ecology.It uses landscape diversity index(H),evenness(E),natural degree(N),contrast degree(C) to study spatial structure and landscape heterogeneity of site resources and thus provides a qualitative-quantitative evaluation method for land planning and management of small ,medium scale areas.The analysis of Yantian District,Shenzhen of China showed that Wutong Mountain belonged to high lanscape ecological sensitivity area,Sanzhoutian Reservoir and Shangping Reservoir were medium landscape sensitivity area and high ecological sensitivity area;Dameisha and Xiaomeisha belonged to medium sensitivity area caused by the decline of natural ecological areas.Shatoujiao,Yantian Pier belonged to low sensitivity area but urban landscape ecological development had reshaped and influenced their landscape ecological roles in a great extent.Suggestions on planning,protection goals an development intensity of each site or district were raised.
