冲击指标应用于保安林地人为冲击之研究
屏东科技大学森林系,中国台湾屏东
摘要:

保安林分布遍及全台湾省,但在自然与社会环境的变迁下,民众对土地资源需求日益迫切,区外保安林常遭非法使用,因此如何有效地订定经营决策,为经营者应注视之问题。本研究以垦丁公园辖区之区外保安林为研究范围,利用1993与2001年SPOT卫星遥测影像为材料,并用监督性分类法中之最大概似法进行影像分类,建立都市、森林、农耕地等3种土地利用类型,分类结果提供监测1993至2001年间保安林之土地变迁。此外保安林地受人为之冲击评估乃采用分类之结果与地理信息系统之空间分析技术,配合保安林地之开发地成长率、农耕地开垦率及保安林地受人为潜在开发率等冲击指标,评估垦丁公园境内各编号保安林所受到的人为冲击。研究结果显示,共有8处保安林所受之冲击最为严重,值得管理者加以重视。

Applying Impact Index to Assessing the Human Impact of Protection Forest
Abstract:

The protection forest lands are distributed scattering among the island in Taiwan,its function in safeguarding the territory is very important.In recent years,because the nature and social environment change quickly,people need more and more land resource;therefore the protection forest land was illegal lyused by the people usually.The purposes of this study are to use remote sensing data to detect the human impact on the protection forest of Kenting Park from 1993 to 2001.Remote sensing data has been used(1993 and 2001 SPOT XS) to establish the land-use database and ancillary with The Bureau of Forestry's protection forest database as the data input of the study.Moreover we used impact indicators of land resources and GIS spatial analysis tools to measure the percent urban growth metric,percent farm growth metric,and percent human impact metric on these protected forest.The result showed that 8 protection forests have serious human impact and attentions should be paied by the manager.
