| Abstract: | To ensure the scientificity, pertinence and implementability of afforestation planning in the 14th Five-Year Plan of Tianjin, the preliminary investigation work was carried out for the 100~150 meters green corridor on both sides of expressways, high-speed railways and first-class rivers. The stand quality of typical forest subcompartment was investigated from three aspects of forest distribution, forest structure and forest health, then the scores of each evaluation index were summarized according to the analytic hierarchy process. After the quality grade of typical forest subcompartment was obtained, the results were extrapolated to the remaining forest subcompartment by using aerial image features, and finally the forest stand quality of green corridor in Tianjin was obtained. |
