生态环境建设中延安市食用菌开发可行性研究

研究了福建省长汀县河田镇八十里河流域采用乔灌混交治理措施恢复的马尾松群落植物多样性研究。结果表明，严重侵蚀地经过整地、施肥、混交胡枝子等措施治理18a后，林下植物种类增加，计有22科30属33种。群落的地理成分以热带成分占优势，生活型以常绿灌木最多，多年生和一年生草本极少，高位芽植物在群落中占据主导地位。群落灌木中以胡枝子、黄瑞木、杉木、油茶和赤楠等树种的重要值较大，草本以芒其占绝对优势，Shannon-wiener等多样性指数以灌木层最大，草本层次之，藤本层最小，而Shannon-wiener均匀度指数藤本层的最大，草本层的最小。

The domestic fungus development is an effective way with ecologic, economic and social benefit. It is also an inexorable demand of improving the people's food structure, economic smoothly developing, and quitting cultivated land to return the forest. Yan'an city is located in the north west edge region of China, the natural condition, geography factors, and the western part development policy have supported a good chance and beneficial future for domestic fungus development. The domestic fungus development is also the fundamental demand of the beauty mountains and ecological agriculture construction. By taking necessity and feasibility analyzing on domestic fungus development according to the domestic fungus production and developing trend of China and combine Yan'an ecological environment construction with domestic fungus development, the ecological industry garden and farmer's domestic fungus development model are put forward, and the specific designing and analyzing on edible ecologic industry garden are taken.
