【摘要】 通过对江苏沿江8市古树资源和长江江苏段2岸1 km范围内森林中各树种资源分布调查，结合长江防护林造林树种选择相关研究，筛选出适用于长江江苏段防护林造林树种59个。分别针对沿路区、滨水区和滩面区3种生态位特点，通过生态效益、景观效益和社会效益3类共10个指标，采用定量与定性研究相结合的方法，对这些树种进行综合评价、排序和分类。结果表明：3种生态位上各造林树种均可分为3类，第1类树种3种生态位可作为优选树种分别有15, 7, 7个；第2类3种生态位作为一般树种，分别有22, 40, 29个；其他可作为备选树种。结合沿江不同造林环境的特点和相关树种的特殊适应性，提出了相应的树种选择和配置建议。更多还原

【Abstract】 Fifty-nine afforestation species were selected for the shelter forest through investigation for the dominant species resources of old or famous trees and the tree species distribution from the forest within the 1 km range of both sides along the Yangtze River in 8 cities of Jiangsu Province, and integration research on the tree species selection for the Yangtze River shelter forest. For the characteristics of the dike trunk area, the waterfront area and the beach area, 10 indexes of ecological, landscape and social benefits were determined for comprehensive evaluation, sort and classification of these species, by using scientific data research and expert consultation. The results showed that 59 species could be classified into three types in each ecological area. Type 1, including 15, 7 and 7 species respectively, was of main priority. Type 2, induding 22, 40 and 29 species respectively, was of general use, and another few were candidates. Combining the land occupation condition and the applicability of tree species, corresponding tree species and configuration were proposed.更多还原
