森林蔬菜是指自然生长或无干扰栽培在无污染、生态环境良好的原始天然林区或次生天然林区,地上部分可加工食用的木本、草本、竹类和蕨类等森林植物 [1-2]。作为森林资源的组成部分,森林蔬菜在林业生产经营以及林产经济中有着重要地位,由于生境良好,无农药、激素污染,富含各种维生素、氨基酸和微量元素,对人体十分有益,常被冠以“林海山珍”之美称。
湖南省湘西地区森林资源丰富,根据龚双姣等[3]人调查显示,湘西地区有种子植物类的野菜共计87科119属335种,大多数都是属于森林蔬菜的范畴,可以生长在林内或林缘,可食用野菜中以菊科所占种类最多,其次是蝶形花科、禾本科等,其中叶菜类有251种,根茎类有39种,花菜类有21种,果菜类12种。以种子供食的有12种,目前湘西地区已经有60多种森林蔬菜得到简单开发[4]。
