喀斯特地区林下养鸡技术六措施

桐梓县属于内陆省份喀斯特地区，广大农村森林和灌木林资源较为丰富，空气清新，适宜养殖林下养鸡。通过选择合适的品种，舍饲和林地放养相结合，以自由采食林间昆虫（或采食人工育虫），啄食杂草为主，人工补饲为辅，饮山中无污染的天然矿泉水，生产出天然的优质商品鸡。笔者根据我县特有的喀斯特地貌，结合养鸡业现状，总结出林下养鸡的技术措施，具体如下，仅供参考：

Probabilistic Classification of Tree and Shrub Vegetation on Phytogeographic System

The phytogeographical system for vegetation classification splits the vegetation in first level types： forest and grasslands. The forest type can be recognized in tropical rain forest and seasonal depending on the environmental conditions. This determines the occurrence of deciduous species in big or small quantity. And the grasslands are Savannah in majority. This work proposed probabilistic methods to classify these vegetation types based on priori occurrence of species. The test was carded out with forest inventory data using ten vegetation fragments in farm of Embrapa and Cascata＇s park in Sete Lagoas city, Minas Gerais, Brazil. The distribution of species with occurrence in different types was adapted to set theory and Bayes theorem. In this way, it is possible to calculate belonging of species on vegetation types. The results were compared with usual classification. The main contribution of probabilistic methods was to increase the information to classify tree and shrub vegetation inventoried. It is especially recommended for transition regions between vegetation types.
