Study On Soil And Water Conservation Monitoring Information System Of Development And Construction Projects

Soil and water conservation monitoring of development & construction projects is a process of implementing real-time monitoring dymamic change of soil & water loss and contorl, analyzing and estimating soil and water loss disater and control benefit of development and construction projects. At present, the work of information management and data analysis is operated simply combined with human and computer. Under this mode, the automatic and scientific degree is low, the work efficiency and result precision is not enough. The development of new position and technoques has put forward newer and higher demand of the information management of soil and water conservation monitoring of development and construction projects.This research constructs a relatively uniform monitoring indicator system which is divided to three levels that are indicator group, indicator subgroup and indicator. The indicator group is consist of five groups, which are soil and water loss influence factors indicator group, soil and water loss status indicator group, soil and water loss disaster indicator group, soil and water conservation measure indicator group, soil and water conservation benefit indicator group. Then it ascertains twelve indicator subgroups and one hundred and three indicators baded on the indicator group, and puts forward monitoring methods and frequency of each indicator.This research puts forward a reasonable assignment of soil and water conservation monitoring. The monitoring sub area is plotted based on soil and water loss type, terrain and physiognomy type, land use type and function cell type of the project. Different kinds of monitoring points are implanted in each sub area for implementing dynamic monitoring of different monitoring indicators to obtian the basic data of each indicator's status. Then the data is used to derivative the entire status of indicators in the sub area even the whole distriction.This research does a detailed operation and data analysis of management organ and implement department of soil and water conservation monitoring.It synthetically applies advanced technoques such as 3S technoques, computer network technoque, database technoues, management information system technoque, and so on, and designs a soil and water conservation monitoring management information system of development and construction projects which can realize data collection, processing, storage, management, analysis and decision-making application. This system, which contains a desktop version and a network version, choses Region Manager as development platform, Access as relation data management, file as figure and multimedia data management. It adopts multi-tier structure and compenent (Compenent Object Model and Compenent Object Model Plus) as main develop technoques, designs five subsystems which are data input, management of basic project information, soil and water conservation monitoring design, management of soil and water conservation information, achievement output. Each of these subsystems has its own function. All of them form an organic system.The result of this research could be applied as information management and data analysis tool for the monitoring management organs and the monitoring departments to improve the work efficiency and result precision. It will be help to standardize the behavior of soil and water conservation monitoring of development and construction projects, provide gist for forecasting the soil and water loss and establishing preventing and controlling scheme in future.The system is helpful to data accumulation. It will provide foundation for data mining and model establishment. And it's also of great significance for mastering the dynamic changes of soil and water loss of development and construction projects throughout the nation.
