The significance of studying on the project--technologies for the establishment of protection forest system at hilly area of Hunan was analyzed and discussed in this paper By using one county's protection forest as the research objecb, the essentiality and importance of species selection, arrangement of tree species,optimal forest structure and management of agro-forest were discussed Also the great role of demonstration forest played in advancing the establishment of county's protection forest was emphasized Based on the analysis of natural resource status, environment and society characteristics, a research process combined the experimental and demonstrational methods, qualitative and quantitative analysis was designed Then experimental and demonstrational forests were arranged and sub-project study process was worked out Based on the great deal of information collected from abroad and home publications done previously, the development situation and trends of protection forest studies on forest benefits, tree species construct, stand type, management of agro-forest and capacity of water and soil conserved with protection forest were summarized, which provided a foundation for the plan of studying on the erosion-protected and soil conservation agro-forest system
