Abstract
ABSTRACT
Forest Deforestation Analysis is based on land cover, where land cover is divided into two classes of forest land cover and non-forest land cover class. Deforestation is a forested area that turns into a non-forest area. Land cover uses high resolution imagery with manual image interpretation (digit on screen) method. This study aims to determine the extent of deforestation and the rate of deforestation every year so that it is known how much carbon is lost from the impact of deforestation. The method used in this research is quantitative descriptive with carbon calculation which has been determined by the unit of weight for several classes of land cover. The results of research on forest deforestation were 319.92 ha with a deforestation rate of 38.57 ha per year, causing loss of 81.724.7 tons of forest carbon C. Accuracy test of images carried out using confusion matrix (comparison of image interpretation with field conditions) with an accuracy of 92,31%.

森林砍伐分析的基础是土地覆盖,土地覆盖分为森林土地覆盖和非森林土地覆盖两类。森林砍伐是指森林地区变成非森林地区。土地覆盖采用高分辨率图像与人工图像解译(屏幕数字)方法。这项研究的目的是确定森林砍伐的程度和每年森林砍伐的速度,以便了解森林砍伐的影响造成了多少碳的损失。本研究使用的方法是定量描述的碳计算,碳计算是由几个类别的土地覆盖的重量单位确定的。森林毁林研究结果为319.92 ha,毁林率为38.57 ha /年,造成森林碳c损失81.724.7 t。使用混淆矩阵(图像解译与野外条件对比)进行图像精度测试,精度为92,31%。关键词:人工图像解译,毁林率,精度检验
