Based on GIS technology and by using moving window method, the characteristics of landscape pattern in Northeast China in 2006 and the relationships between these characteristics and environmental factors such as precipitation, air temperature, altitude and human activities were studied. In the study area in 2006, forest land had the largest proportion, followed by the cultivated land, occupying 61.69% and 25.11% of the total respectively, and the landscape diversity had the characteristics of circle-zoning structure, which provided a buffer region for fragmented and sensitive regions, making the adverse ecological consequences be reduced to or restricted in a definite scale. The correlation coefficients of landscape indices with precipitation and air temperature were less than 0.4, and those with altitude were less than 0.07, illustrating that the heterogeneity of landscape pattern in study area was not dependent on single natural factors.
基于地理信息系统（GIS）技术，采用移动窗口法，研究了2006年中国东北地区景观格局特征及其与降水、气温、海拔等环境因子和人类活动之间的关系。2006年研究区内林地比例最大，其次是耕地，分别占总面积的61.69%和25.11%，景观多样性具有圈层结构特征，为破碎化和敏感区域提供了缓冲区域，使不利的生态后果降低或限制在一定范围内。景观指数与降水和气温的相关系数小于0.4，与海拔的相关系数小于0.07，说明研究区景观格局的异质性不依赖于单一自然因子。
