| 摘 要： | 植被净初级生产力是评价和估计生态系统的碳源或碳汇作用的关键因子,对了解陆地生态系统的演化和判定生态系统碳汇和生态调节过程具有重要的作用.以黑龙江省带岭林业局为例,基于SuperMap IS.NET平台,选用SQLServer 2005数据库存储数据,使用C#为主体语言开发黑龙江省带岭林业局NPP信息发布系统,初步实现图形与属性的双向查询、NPP时间曲线绘制以及简单的NPP值与高程、坡度、坡向等地形因子的数据分析,对该区域森林生态系统生产力、生物量以及碳循环方面的研究提供方便快捷的数据支持.

| Abstract: | The NPP is to evaluate and estimate ecosystem carbon or carbon sequestration, which is a key factor in understanding the evolution of terrestrial ecosystems and ecosystem carbon sequestration and plays an important ecological role in determining the ad- justment process. In this paper, Dailing Forestry Bureau of Heilongjiang Province is used as an example to develop Dailing Forestry Bureau of Heilongjiang Province NPP information distribution system based on SuperMap IS. NET platform, SQL Server 2005 data- base, and C# language. The functions of graphics and attributes bidirectional query, NPP time curve drawing, as well as data analy- sis between NPP values and elevation, slope, aspect, and other terrain factors have been realized, which provides a convenient data support for regional forest ecosystem productivity, biomass, and carbon cycle research. |
