GIS在森林生态系统服务功能中的应用——以大连市区为例

The Application of GIS in Forest Ecosystem Service

地理信息系统(GIS,Geographic Information System)是20世纪60年代开始迅速发展起来的进行地理科学研究的新技术,它具有强大的空间数据处理与空间分析功能。在森林生态系统服务功能中引入GIS技术将大大提高森林生态系统服务功能评估的合理性,提升森林生态系统服务功能评估的水平。该文结合辽宁省大连市市区森林生态系统服务功能评估的实践,首先通过对市区林分因子的调查,遥感图片的校正,评估因子的选取,空间模型的建立,最后计算出选取的林分因子的各项指标,对市区森林生态系统服务功能,在空间上有一个直观的展现,为以后进一步评估和领导决策提供依据。

Geographic Information System（GIS）is In 1960 s, it began to develop rapidly in the new technology, which has powerful spatial data processing and spatial analysis function. The introd uction of GIS technology in forest ecosystem service function will greatly improve the rationality of forest ecosystem service function evaluation, and improve the level of forest ecosystem service function evaluation. Combining with the practice of Liaoning Province Dalian city urban forest ecosystem service function evaluation. First of all, through the investigation of urban forest factors, correction of remote sensing images, selection of evaluation factor, the establishment of model space. Finally, calculate the stand factors selected indicators, on urban forest ecosystem service function, in space have an intuitive show. Provide a basis for further evaluation and leadership decision.
