Scenic beauty evaluation of plant landscape in Yunlong Lake wetland park of Xuzhou City, China

The plant landscape of Yunlong Lake wetland park in Xuzhou city was studied in this paper, 57 plant landscape photos were evaluated with SBE (scenic beauty evaluation) method, and the factors affecting the scenic beauty were analyzed. The results showed that (1) there was significant correlation between different evaluation groups on the scenic beauty of plant landscape; however, the convergence of different people in the evaluation of “beautiful” plant landscape was significantly higher than that of “ugly” plant landscape. (2) According to the comprehensive SBE mean values of 57 plant landscape photos, 31 were negative and 26 were positive. The order of SBE mean values of different types was plant landscape beside buildings or sketches (0.1882) > plant landscape on both sides of the roads (0.1667) > waterfront plant landscape (− 0.0085) > typical plant community (− 0.1729); the k-mean clustering grouped 57 photos of plant landscape into 5 categories: the proportion of “excellent, good, medium, average, and poor” was 5.26%, 24.56%, 29.82%, 26.32%, and 14.04%, respectively. (3) Linear regression analysis showed that the beauty of plant artistic conception was the main factor affecting the SBE of plant landscape. The regression equation was SBE = − 1.3 + 0.335 × (plant artistic conception). (4) The combination of plants and other landscape sketches was more favored by people; waterfront plant landscape and typical plant communities had a low degree of beauty in Yunlong Lake wetland park, which needed to be matched reasonably to create a better plant artistic conception.
