Abstract:
Tianmu mountain and Qingliangfeng nature reserve are important germplasm resources of plant resources in the Yangtze River Delta region. In order to meet the needs of urban green space development, scientific development, and utilization of existing woody wild ornamental fruit plant resources, the natural education value of woody wild fruit plants in the reserve was evaluated and analyzed through field investigation, literature verification analysis, and analytic hierarchy process,. The results showed that: 1) There were 344 species of wild ornamental fruit plants in the protected area, belonging to 59 families and 145 genera. 2) Based on the nature education and the regional characteristics and application value of the flora of East China, the evaluation system of the natural education value of woody wild ornamental fruit plant resources was put forward. The 145 species of ornamental fruit plants were selected by the analytic hierarchy process and was divided into four grades. The weights of the constraint layers of the evaluation were: ornamental value (C1) 0.4434, teaching value (C2) 0.1692, and application value (C3) 0.3874. 3) The evaluation of plant development and utilization grade was partitioned using hierarchical analysis: Grade I has 19 plants that have extremely high ornamental value and should gain extensive exploitation; 31 plants in grade II that have high development and utilization value; 26 plants in grade III that have moderate exploitation value; 69 plants in grade IV that have low exploitation value. 4) Based on the evaluation results, a plant-type, ornamental and eco-friendly plant community allocation model suitable for application in the Yangtze River Delta region is proposed.
