Abstract: In order to know the vegetation characteristics and nutrient variation in the beginning period of ecological protection engineering on the rock slope, a study was done to test main community characteristics such as species composition, coverage and height, and soil nutrient factors such as organic matter and available nutrient elements. The research has been taken monthly on three slopes with different aspect and gradient in two years after vegetation planted. Results showed that: 1) There was significant seasonal changes on quantitative characteristics of plant communities generally at the early period since artificial vegetation planted. During the first year the number of species, which most belonged to planting’s, was few, and enriched greatly with invasion of local native plants in the next year. There were two withered periods of slope vegetation in a year, hot summer and cold winter. Living part coverage of the community was minimum during later winter and spring, recovered greatly from May and ascended until July, declined in August and September, then ascended again in October and got to the best in November. Community height in second year was higher than that in first year. 2) Content of available nitrogen and phosphorus decreased fluctuantly in two years, and lower than that of the beginning of artificial vegetation established. Available potassium content in No.1 and No.2 slopes declined after two years waved changing, but increased in No.3 slope. Content of organic matter increased greatly after fluctuant movement in first year, declined significantly in first three month of the second year, then stabilized until the end of the year. The content of organic matter at the end of the second year was lower than that at the same time of the first year. 3) There was obvious difference of species component and community coverage among three slopes in first two month of the beginning period, with the slopes were covered generally, slope aspect and gradient had no obvious influence to community characteristics.
