立地评价系统的设计与实现

Design and implementation of site evaluation system

针对目前基层林农与林场在森林经营管理中的立地评价问题,探讨了利用林分生长模型对有林地进行评价的方法与技术,建立了以定距等分算法为核心,采用好、中、差立地等级对有林地进行评价的方法,设计了林分生长模型库,实现了生长模型解析算法。在此基础上,设计了立地评价系统工作流程和立地评价系统架构,结合无林地评价开发了基于浏览器与服务器体系结构的综合立地评价系统,从而有效满足了在只有林分生长模型情况下的立地评价需求。

Aimed at the problems of site evaluation encountered by farmers and forestry farms in forest management,the evaluation method for woodland with the good,middle and poor site level based on distance uniform algorithm is constructed after discussing the woodland quality evaluation methods and technologies with stand growth models.The stand growth models database table is designed and growth model parse algorithm is implemented.On the basis of the study,the workflow and structure of site evaluation system are designed.The comprehensive site evaluation system is developed based on Browser/Server structure,so as to effectively meets the site assessment requirement in the case of only having growth models.
