Problems and proposals of vegetation restoration techniques in rocky slopes
This paper analyses the vegetation restoration problems in rocky slopes, such as brittle ecological effect, difficult maintenance, high construction cost, and non-permanence of the revegetation effect. Based on soil properties, degree of revegetation difficulty and restoration target, the paper divides rocky slopes into two kinds ： one is the hard rocky slope, the other the rotten rocky slope，emphasizing that the revegetation in the rocky slopes should follow the principles of stabilization of the slope and the vegetation succession. It mainly discusses the greening method by using lianas in hard slopes, and proposes that basic research and new techniques should be applied to the rotten rocky slope on the premise that the current techniques have been mature in this field.

Study on vegetation restoration effect on rocky slope of the expressways in eastern Jilin Province
Based on expressway construction engineering and theory of vegetation restoration and reconstruction,this paper discusses the restoration effects of vegetation protection engineering of rocky slopes in Jilin Province.The results show that ：1)In the process of vegetation restoration on rocky slopes,the model of native species combined with exotic selection species should be taken as species configuration pattern.And we should take the pattern of herb and arbor (shrub)as the ultimate community；2)On the initial stage of vegetation restoration project,diversity of plant communities changes apparently.The invasion of local pioneer species indicates the artificial slopes have been integrating into the local environment as a whole ；3)We should choose the drought tolerance plant species,shade tolerance plant species and fast-initial-growth-rate plant species first;4)Nursery block technique is suitable for arbor (shrub)transplantation in vegetation restoration on rocky slopes,it is a new transplantation model of great potentiality.

Application of analytical hierarchy process method to comprehensive evaluation in ecological restoration of abandoned quarry
The fundamental theory and method for comprehensive assessment of ecological restoration of abandoned quarry, using the analytical hierarchy process (AHP), was introduced in this paper.Comprehensive assessment index system in ecological restoration comprehensive assessment of abandoned quarry is set up and the weight of each index is calculated by AHP. The results show that among the 21 indexes of the system, 5 indexes with the largest weights were ranked as follows: species diversity, community structure,water and soil conservation, vegetation coverage, ornamental value. This viewpoint indicates that the primary factor of assessing ecological restoration of abandoned quarry is of ecological benefit. Meanwhile, the result also shows that AHP is an advantageous method over ordinary qualitative analysis for the assessment of ecological restoration of abandoned quarry，and is also conducive to draw the conclusions in line with the actual situation, and to provide scientific foundation for demonstrating the feasibility of the project.

Application of engineering revegetation technology in ecological rehabilitation of the roadside slope
The roadside slope is part of the road system. Roadside slope management and ecological rehabilitation are of importance in road construction. The application of engineering revegetation technology in slope management and the ecological rehabilitation are introduced in this paper. Engineering revegetation technologies applied in embankment slope include geocell ecological technology and framework grass covering.The technologies applied in soil cutting side slope are mainly hydraulic seeding, framework grass covering and 3D vegetation net. The technologies applied in weathered rock area are 3D net scattering, channel covered with net and scattering, geocell covered with net and scattering and concrete and vegetation protection. The technologies applied in weak weathered rock area is mainly mixed scattering and in soil slope is mainly foreign soil scattering. This paper discusses the problems with and the prospects of the application of the engineering revegetation technologies.
