Using the methods of investigation and GPS position, tourism resources of Wolong Villa in Hebei province are investigated. Then tourism planning are made, schemes planed are evaluated by using the methods of landscape ecology. Then some plants are planned, such as sour jujube, dong jujube, li jujube, yueguang jujube, wild vegetables, persimmon, cerasus humilis and altered the plant type of ornamental garden. Some trees are planned to plant such as Pyrus betulaefolia Bunge，Koelreuteria paniculata Laxm, and Ailanthus altissima Var.. And some aspects are also planned. For example, ecological rain-collection exemplary base, exhibition room of rocket eliminating lightning, Wolong temple, goldfish pool, fish-watching corridor, store, sight-viewing pavilion, road, park and washing room. Using landscape indices in the aspect of patches level and landscape level as quantity indices, it evaluates planned effect. Some conclusions are put forward that though landscape fragmentation indices are increased after planning, centralizing degree of landscape types strengthened. Diversity index, Dominance index and Richness index are also increased，so esthetic qualities are improved, tourism facilities are more perfect, and sightseeing periods are longer. This evaluation method has certain feasibility and reference value in the .screening of planned scheme.
