张家界野生蔬菜资源调查

根据植物地理学原理,采用民间走访和实地调查相结合的方法,对张家界野生蔬菜资源的种类、分布、储藏量、食用价值、食用部位、食用季节、保健功能和利用现状等进行了调查研究.结果表明:张家界野生蔬菜资源约有36科65属74种;分布在海拔250～2 030 m,且高海拔地区较低海拔地区分布多;食用部位多以茎、叶为主,根、根茎、块根、块茎次之,花最少.提出了改进加工工艺、探索深度加工、以开发储量较大野生蔬菜资源为龙头带动储量较小野生蔬菜资源的开发、开展驯化栽培、保护和恢复生态、以生境养山珍等开发利用措施.

Investigation of wild vegetable resources in Zhangjiajie region

According phytogeography principle,by interviewing mountain people and conducting field survey type,reserves,vertical distribution and food value,edible parts,harvesting season,health functions and the present utiliaztion situations of wild vegetable resources,etc. in Zhangjiajie region was investigated. As a result,about 36 families 65 generas 74 wild vegetable species are discovered,vertical distribution at an altitude of 250 ～ 2 030 m,and there are more species in the high altitude than in the low areas. For most of them,the main edible parts are stem and leaves, while roots,rhizomes, tubers, earthnut are secondly edible,flower is the least. The following measures were put forward:improving techniques of processing,exploring the depth of processing,motoring the development of smaller reserves headed by that of larger reserves,carrying out domestication cultivation,protecting and restoring ecology,and establishing a habitat to cultivate precious mountain vegetables.
