Abstract

Abstract The purpose of this paper is to evaluate the forest health condition in the area of Hydropower plant Gabčikovo using the digital multispectral aerial images from 2011 in the section Dobrohošt - Sap. We proposed a new innovative procedure of creating the forest mask in the image processing. It concerns a process of defining tree crowns, where we combined subject and raster oriented approach of the image classification. We evaluated forest health condition on a selected forest mask using the method of twophased sampling with regression. The indicators of health condition were tree defoliation and presence of heavily damaged trees and snags in the stands. Defoliation was used to compare the current forest health condition in the concerned area with the data from 2008. Presence of the snags as the result of severe damage is interpreted in terms of stand types related to site conditions. Field survey proved presence of invasive and non-native tree species and plants. Based on the result, we have formulated recommendations for further forest monitoring in the Danube River inundation

摘要:本文利用2011年Dobrohošt - Sap部分的数字多光谱航空图像对gab ikovo水电站区域的森林健康状况进行了评价，提出了一种新的创新方法，即在图像处理中创建森林掩模。它涉及一个定义树冠的过程，其中我们结合了主题和面向栅格的图像分类方法。采用两阶段抽样回归的方法对选定的森林掩膜进行森林健康状况评价。健康状况的指标是树木的落叶和林分中存在严重受损的树木和障碍。采用落叶法对相关地区的森林健康状况与2008年的数据进行比较。由于严重破坏而出现的障碍是根据与现场条件相关的林分类型来解释的。野外调查证实存在入侵和非本地树种和植物。在此基础上，我们提出了进一步监测多瑙河淹没森林的建议
