昆山生态森林公园野生观赏植物资源开发评价研究

Exploitation Priority of Wild Ornamental Plant Resources in Kunshan Ecological Forest Park

为进一步丰富昆山城市园林绿化植物品种并积极开发利用乡土野生观赏植物资源,选取昆山生态森林公园内的60种野生观赏植物资源作为研究对象,通过构建由观赏价值系数、濒危系数、繁殖难易系数、抗性系数、蕴藏系数和生境适宜性系数6项指标组成的评价体系进行评价分析,确定60种观赏植物的优先开发序。研究结果表明:第一类的夏至草、益母草等15种植物在昆山极具推广应用价值,第二类马齿苋、野菊等6种植物也可在园林建设中积极推广,第三类以及第四类共39种植物的推广应用价值意义不大。通过综合评价,可为昆山地区野生观赏植物资源的开发利用提供参考。

In order to further enrich the urban landscape plant varieties and actively use the local wild ornamental plant resources in Kun Shan, 60 species of the wild ornamental plants in Kunshan Ecological Forest Park were selected as the research object. An exploitation priority evaluation model consisting of ornamental coefficient, endangered coefficient, breeding coefficient, resistance coefficient, volume coefficient and habitat suitability coefficient was constructed. The exploitation priority of the 60 species of wild ornamental plants was determined by assigning different weights for the above 6 coefficients. The evaluation results showed that 15 species including Lagopsis supina, Leonurus artemisia, etc. were classified into the first level and was the best for popularization and application. 6 species including Portulaca oleracea, Dendranthema indicum, etc. wereclassified into the second level, and should also be applied in park and garden construction. The other 39 species which belonged to the third and fourth level did not have great value for popularization and application.The comprehensive evaluation provides a reference for landscape exploitation and application of wild ornamental plants in Kunshan.
