The forest coverage in China has increased rapidly according to the 7th National Forestry Inventory (NFI). However, the quality of forest is still low, for example 34% of forestry area is plantation whose mortality rate after regeneration is high, standing volume is at low level relatively and stand structure tends to be monoculture. It reveals that there would be some problems at afforestation plan and design and the operation of afforestation projects. The study is carried out to develop an Afforestation Plan and Design Information System. The system in C/S structure is developed by GIS, RS, and spatial analysis technologies, after researches on the operation process of afforestation plan and design, standard form of data and database design, which is for information resources sharing. By taking the system construction in Zhangjiakou as the research case, this paper introduces the system functions design, system framework, database structure, logical and physical design of database. With the foundation of GIS platform, geographic data storage, afforestation plan and
design, afforestation projects management and 2D/3D displaying come true. |
