根据人类干扰对森林景观变化效果大小,把对森林景观产生作用的人类干扰类型分为调控型和变迁型,建立了定量评价人类干扰对森林景观类型相关性影响的综合测度模型.结果表明,人类干扰调整了森林景观的总体格局,改变了森林景观类型间的相关性;从森林景观与人工景观、管理景观的相邻度可以衡量人类干扰的影响程度;人类干扰因素的复杂性及各因素间的关联性,导致各因素对干扰机理存在模糊性,要进一步把握干扰影响的内在规律,必须结合其它方法.

Human disturbance has exerted much changing effect upon forest landscape.According to the changed degree,this paper divides human disturbance into two types： controlled type and varied type.Based on the two types,an evaluation model is established for its effect on the correlation among the forest-landscape types studied.Results show that human disturbance has changed the general pattern of forest landscape as well as the correlation among its types;that the contiguity between forest landscape and artificial landscape,between forest landscape ...
