太鲁阁国家公园高山地区土地资源变迁之调查分析

高山峡谷与丰富的生态环境特色是太鲁阁国家公园重要的自然资产，是以常为国人进行自然探知、环境教育与游憩休闲的场域。然而藉由人类的系列活动，包括道路的开辟、高冷蔬果的种植以及人造结构物的兴建等，大大的改变了高山地区的生态环境。本研究调查太鲁阁国家公园园区海拔1200m以上高山地区土地资源利用情形，针对已被利用的高山环境以不同时期的遥测影像分析，以了解其变化情况。研究显示土地资源的利用是与地貌条件及交通易达性有密切相关；开发区概以公路两侧，并以西段通往梨山、雾社之大禹岭为最。国家公园成立后的开发受到限制是以变异性不大，未来国家公园对园区内自然保育与生态环境维护仍应持续以积极的态度面对，并建构长期监测机制及技术，以做为未来对已开发区之土地经营管理之参考。

Land Resources Change on Taroko National Park High Mountain Region

Due to its uniqueness in geology and geographical position,the high mountain region in Taiwan preserves diverse ecosystems. Nonetheless, human activities in road construction, farming, and man-made structures have accelerated the alteration of the environment in the high mountain region. This research investigates the land resources in the high mountain region of the Taroko National Park over a period of time by employing the remote sensing images of developed areas, which are geographically corrected at different stages. Our study indicates that the utilization oI lands is strongly related to geomorphology and accessibility. The developed areas are mostly along the roads, among which the west of Da-Yu-Lin is the most developed. The Taroko National Park was formally established in 1986 to have the environmental damages under control, and to build up a long term monitoring system for national parks in general on destructive land management.
