潮关西沟生态经济型防护林立地类型的划分

立地分类是森林建设的基础，也是科学经营森林的重要手段。为了营建稳定的生态经济型防护林，持续发挥防护林的生态经济功能，需要对立地条件进行科学的划分。在对潮关西沟的地形、土壤、植被调查的基础上，根据立地类型划分的原则和依据，确定了海拔、坡向、地形部位、土层厚度、土壤质地为立地类型划分的主导因子。并以此为依据将潮关西沟的立地类型划分为3个立地类型小区，5个立地类型组，14个立地类型，为生态经济防护林的规划及建设提供了科学依据。

Site Type Classification of Eco-economic Shelter Forest in Chaoguan West Ditch
