การวิเคราะห์ศักยภาพเชิงพื้นที่และชุมชนเพื่อแก้ไขปัญหาทรัพยากรป่าไม้ในลุ่มน้ำยาง ตำบลป่าแลวหลวง อำเภอสันติสุข จังหวัดน่าน

Abstract

The situation of forest areas has tentatively decreased and transformed to other land uses, through intensive agricultural production. It has resulted to decrease rapidly forest resource of the country. Integration of geo-information technology and the community participation in the survey, collecting and development of spatial and community databases. This leads to resolving forest resource problems and raising the land use efficiency in the Yang small watershed, Pa Laeo Luang sub-district, Santi Suk district, Nan province. This study had purposed to develop the spatial and community databases, analyze the driving forces impacting on land use changes, and investigate spatial and community potentials, produce spatial scenario mapping and collaborating the people awareness to design the alternative land uses. Geo-informatics technology was collaboratively applied, including remote sensing to classify, monitor, and mapping the land use in the Yang small watershed in 2016 with THEOS satellite imagery, and the land use in 2019 with GeoEye-1 satellite imagery integrative with imagery data from the unmanned aerial vehicles (UAV). In addition, geographic information system was applied to analyze the land use change of the Yang small watershed during 2016 to 2019, including the mapping of land use changes with linking to their attribute data. Finally, global positioning system (GPS) was applied to explore and mapping of locations, areas and boundaries of the farmers' agricultural plots.
