为保证天津市“十四五”造林绿化规划的科学性、针对性和可实施性,针对高速公路、高铁、一级河道两侧100~150 m绿色廊道,从森林分布、森林结构和森林健康3方面,对小班的林分质量进行调查,并按层次权重分析法汇总各评价指标分数,得到典型森林小班质量等级后,利用航片影像特征将结果反推至剩余森林小班,最后获得了绿色廊道林分质量情况。 |
英文摘要: |
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. |
