Hedge plants owned many features, including perennial evergreen shrub, ground cover plants with long flowering period, colorful leaf plants, high germination, low maintenance, etc. Hedge needed showed great aesthetic images with high strength maintenance, such as cutting to control their height and growth area. The study tried to do the practical survey and evaluation for the hedge plants in the Sun Moon Lake national scenic area. It also analyzed the homogeneity of shrub cover, the growth vigor, the overall ornamental, maintenance situation and no symptoms of disease and insects for the authorities and maintenance contractors. The surveyed area included the plant management of landscape engineering in the Sun Moon Lake national scenic area. The area divided into eight sites, including A, B, C of Route 21, Shuishe wastewater treatment plant, Xiangshang visitor center, Xiangshang wedding square, Mingtan tunnel, Checheng area. The practical survey was from June 2016 to January 2017 for eight months. The survey content owned the sunshine intensity, soil pH and soil moisture, and the plant survey content included five indicators, covering homogeneity, growth vigor, the overall ornamental, maintenance and no pest symptom rate, total of 5 major indicators of 1-5 points for evaluation It discussed the hedge plants that was found over 3times in the survey area about the growth evluation indicators by using Scheffer afterwards test: the Cigar Flowers (Cuphea hyssopifolia) in the A of Route 21 and Checheng area were better than those in the Xiangshang wedding square for the maintenance situation; The growth intensity of Jungle Flame (Ixora chinensis) planted in the Xiangshang visitor center and Checheng area was better than those in the C of Route 21. The Covering homogeneity, growth intensity and maintenance management of the Common Dracena (Cordyline terminalis) in the A and B of Route 21 were better than those in the C of Route 21; The Covering homogeneity, growth intensity and maintenance management of the Rhododendron in the A of Route 21 and Checheng area were much better than those in the Xiangshang wedding square; The maintenance management of the Nantianzhu (Nandina domestica) planted in the Xiangshang wedding square and Checheng area were better that those in the Xiangshang visitor center; The maintenance management of Golden Queen (Argyranthemum frutescens) planted in the C of Route 21 and Xiangshang wedding were better than those in the Checheng area. The survey findings were showed: the hedge plants after planted was not easy to mix mixed with weeds and miscellaneous rattan with higher covering level. Moreover, it was able to reduce the demand for vascular, and the overall viewing is also better. Therefore, it suggested that the plants grew up slowly planted higher covering level, so that they arrived the situation of complete coverage to avoid weed growth. In addition, the hedge plants owned lower covering homogeneity should improve the conservation strategies for the visitor and animal trampled.
