Soil ecotype may reflects synthetic characteristics of regional soil resources and their ecological factors, and controls productive potency and utilizing direction of regional soil. Division of soil eeotype has a important significance to exploiting natural resources and developing ecological economy in mountain areas. To the soil eco-system in Xianfeng Tree Farm, Yilan county, vertical differentiation of topography causes differentiation of soil ecotypes: valley flat-meadow soil ecotype; valley depression-bog soil ecotype; hills and low mountains-dark brown forest soil ecotype. These ecotypes have different utilizing direction and constructing measures in ecological economy regarded forest as main objects in hills and low mountains areas. The theory of heterogreous symbiosis in landscape ecology is of universal directed significance for how to exploit and construct these ecotypes in mountain areas.

土壤生态类型能够全面反映区域土壤资源及其生态因子的综合特性,规定和制约着区域土壤的生产潜力和利用方向。土壤生态类型的划分,对山区自然资源的立体开发,进行山区生态经济建设,具有重要意义。 依兰县先锋林场土壤生态系统,由于地形的垂直分化作用,分化为不同的土壤生态类型,有河谷平地草甸土生态类型;低山丘陵暗棕壤生态类型;河谷洼地沼泽土生态类型。这些不同的土壤生态类型在以林为主的低山丘陵区的生态经济建设中,其利用方向和建设措施不同。 景观生态学异质共生理论,对山区各种土壤生态类型的合理开发建设具有普遍指导意义。

土壤是生态系统最基本的资源,也是不可再生的物理组分,各类经营活动必须以维护土壤的持续利用为前提。森林采伐作业不可避免地会对森林生态系统产生一定的扰动。其中最为主要的方面是采伐作业后林地土壤理化性质的改变。本文从生态学的原理出发,阐述了采伐作业引起土壤理化性质改变的机理,并分析了这些变化对森林生长和森林生态系统经营的影响。
