荆州松滋市曲尺河蕨类植物资源与观赏特性评价
Evaluation of Resources and Ornamental Characteristics of Fern in Quchi River, Songzi City, Jingzhou

以湖北省荆州松滋市曲尺河为调查地，对当地蕨类植物资源的观赏性状进行调查统计，通过层次分析法(Analysis Hierarchy Process, AHP)对26种蕨类植物进行观赏价值综合评价，选择根状茎、叶片、孢子囊群三个评价准则和15个评价因子建立曲池河蕨类植物观赏性状评价体系，对26种蕨类植物进行观赏等级划分，以期对蕨类在园林景观中的运用提供依据。结果表明，在一级指标中，叶片所占权重最高，是影响蕨类植物观赏价值最重要的指标。在二级指标中，叶形、幼叶颜色、叶稀有度、叶色对蕨类植物观赏价值的影响权重均超过10%，对评价结果有较大影响。参评植物中，综合评价Ⅰ级的有苏铁蕨(Brainea insignis)、荚囊蕨(Struthiopteris eburnea)、海金沙(Lygodium japonicum)、银粉背蕨(Aleuritopteris argentea)、乌蕨(Odontosoria chinensis)、卷柏(Selaginella tamariscina)，这六种蕨类植物观赏价值较高，具有较好的园林应用前景。
Taking Quchi River, Songzi City, Jingzhou, Hubei Province as the survey site, the ornamental characteristics of local ferns resources were investigated and counted, and the ornamental value of 26 species of ferns was comprehensively evaluated by the analytic hierarchy process (AHP). Three evaluation criteria and 15 evaluation factors were selected to establish the appraisal system of ornamental characteristics of ferns in Quchi River, The ornamental grade of 26 species of ferns was divided in order to provide a basis for the application of ferns in landscape architecture. The results showed that the weight of leaves was the highest among the first-grade indexes, which was the most important index affecting the ornamental value of ferns. In the secondary indicators, the weight of leaf shape, young leaf color, leaf rarity and leaf color on the ornamental value of ferns is more than 10%, which has a great impact on the evaluation results. Among the participating plants, the comprehensive evaluation of grade I included Brainea insignis, Struthiopteris eburnea, Lygodium japonicum, Aleuritopteris argentea, Odontosoria chinensis, and Selaginella tamariscina. These six kinds of ferns have high ornamental value and have good garden application prospects.
