林业生态工程信息分类与编码体系研究

按照科学性与系统性、唯一性、实用性、兼容性、完整性和可扩展性的原则, 根据林业生态工程的系统构造和建造目的, 将林业生态工程分为生态保护型林业生态工程、生态防护型林业生态工程、生态经济型林业生态工程和环境改良型林业生态工程等4大类, 细分为天然林资源保护工程等24小类。林业生态工程信息分为基础信息、设计信息和验收管理信息3大类, 并对林业生态工程进行编码, 编码结构由大类、小类、工程码和扩展码共4级8位码组成。林业生态工程信息数据项如已有相关的标准则沿用已有标准中的相应代码, 否则根据信息属性自行分类与编码。

Research on classification and coding of forestry ecological engineering information

According to system structure and construction goal, following the principles of scientificity, systematicness, uniqueness, compatibility, integrity and extensibility and using traditional classification methods, forestry ecological engineering can be divided into four main categories including pro-conservation engineering, eco-protecting engineering, eco-economical engineering and environment-improved engineering. These four types of engineering are subdivided into twenty-four sub-categories such as natural forest protection engineering. Forestry ecological engineering information is divided into three types, namely, basic type, designing type and managing type. On the basis of classification, every item is encoded. The code structure of items includes four parts: main category code, detailed category code, engineering code and extended code. Items codes adopt relevant codes in the existing standards. Otherwise, they will be classified and encoded by users themselves. ［Ch, 1 fig. 3 tab. 12 ref.］
