基于地理信息系统技术，采用移动窗方法，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、人类活动等环境因子的关系。在2006年研究区内，林地所占比例最大，其次是耕地，分别为61.69%和25.11%，景观多样性具有环带结构特征，为碎片化、敏感区提供了缓冲区，使其对生态环境的不利影响得以减少或限制在一定的规模内。景观指数与降水量、气温的相关系数均小于0.4，与海拔的相关系数均小于0.07，说明研究区景观格局的异质性不受单一自然因素的影响。
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.
