摘要
借助遥感和地理信息系统及其集成技术,以闽江流域林地多年平均温度、多年平均降水量栅格数据库及主要土壤质量因子栅格数据库为基础,建立森林气候生产力和森林生产力栅格数据库.运用ERDAS建模功能及动态聚类生成闽江流域林地森林气候生产力和森林生产力分布图.通过对2个生产力空间分区分析,全流域各生产力总体空间分布上大致呈从东南向西北略有递增的趋势,中部和西北部较高,东南和西部相对较低.研究结果为闽江流域森林资源合理利用提供决策和技术支持.
The grid database of forest climate productivity and forest productivity was constructed according to multiyear average temperature and rainfall datum by RS, GIS and other integrated technology in Minjiang watershed. The distribution map of forest climate productivity and forest productivity in Minjiang watershed was generated by using ERDAS model and dynamic cluster. The results showed that the overall spatial distribution of the two productivities presented slightly increasing trend from southeast to northwest in general and it was higher in middle and northwest parts and relatively lower in southeast and west parts. The results provide the decision and technology support for forest resources rational utilization in Minjiang watershed.
