生态弹性力反映了生态系统的抗干扰能力，是实现可持续发展的基础。不同尺度的生态弹性力具有明显不同的特征，对其尺度效应的研究不仅能够更为深入的理解生态弹性力作用机制，更为不同尺度下生态系统保护与多尺度协同发展规划提供基础。因此，本研究在明确生态弹性力概念的基础上，提出其空间作用尺度划分标准，对生态弹性力空间尺度效应的内涵及特征进行了深入分析，明确了生态弹性力尺度效应包含了粒度效应和幅度效应两个方面，并形成生态弹性力空间尺度效应的表征方法。以生态弹性力空间尺度效应理论研究为基础，确立了生态弹性力空间尺度效应的研究方法，选取呼伦贝尔市、呼伦贝尔市森林区和鄂伦春自治旗作为三个不同的研究幅度，并基于5km、10km、20km、50km和100km五个粒度进行尺度效应理论体系应用研究。本研究主要得到以下结论：（1）生态弹性力是在一定的时间及空间尺度下，生态系统演替处于相对稳定的阶段，生态系统能够承受外部扰动的能力，是人类作用与自然条件的综合表征。本研究结合生态系统特征并兼顾行政尺度将生态弹性力作用尺度划分为超宏观尺度、宏观尺度、中观尺度和微观尺度，并提出了相应的划分准则。（2）生态弹性力尺度效应研究包括粒度变化和幅度变化两个方面，幅度效应表现为在不同幅度下组成生态弹性力的影响因子会有所差异，生态弹性力表现出的总体特征也会有所差异；粒度效应则表现为特定的研究幅度下具有一定的适宜评价粒度，适宜评价粒度必须保证足够的空间异质性和空间自相关性。（3）通过变异系数确定具有足够空间变异性的指标作为生态弹性力评价的基础指标，并通过半变异函数确定适宜评价粒度，识别具有良好空间结构性的指标作为生态弹性力的最终评价指标，从而形成生态弹性力尺度效应分析方法体系。（4）对呼伦贝尔市、呼伦贝尔市森林区以及鄂伦春自治旗三个不同幅度生态弹性力单要素尺度效应以及综合尺度效应进行分析，确定三个幅度下生态弹性力的评价指标体系，以及三个幅度下的适宜评价粒度分别为50km、50km和20km。在该适宜粒度下对生态弹性力进行评价，确定不同幅度下生态弹性力的支撑等级，并对集聚区进行识别，从而确定重点保护区域以及不同幅度生态弹性力的保护目标。

Scale is one of the foundations in ecosystem evaluation. Scale issues are also a major problem plagued ecology which are caused by complexity of ecosystem. Ecological resilience reflects the capacity that ecosystem can accept the disturbance. It is the foundation to coordinate social economic system and ecological system. Ecological resilience has different characteristics in different scales. The study on the scale effects can not only understand the function mechanism in-depth, but also provide the basis for ecosystem protection and development in multiple scales. Therefore, the ecological resilience concept were defined in this study, and its spatial scale classification standards were proposed. The scale effects of ecological resilience were in-depth analyzed in order to study its connotation and characteristics. According to the thoery of ecological resilience scale effects, the methods for analysis of ecological resilience scale effects were built. In this study, three different research extents which included Hulun Buir City, Hulun Buir forest region and the Oroqen Autonomous Banner were chosed as study areas, and five sizes 5km, 10km, 20km, 50km and 100km were included to studied with ecological resilience scale effects theory. This study obtained the following conclusions:（1）Ecological resilience was defined as in a certain time and spatial scales, and ecosystem succession in a relatively stable phase, the capacity of ecosystem could stand the external disturbances. It reflects the combined action of ecosystem and human activity. Ecological resilience in high level means the ecosystem could provide more ecosystem service. Ecological resilience depends on the situaiton of climate, terrain and landscape. Scale effects on ecological resilience include grain effects and extents effects. According to the characters of ecosystem and administrative division, we defined five scales for ecological resilience evaluation, that is super macro scale, macro-scale, meso-scale and micro-scale.（2）The spatial heterogeneity and spatial autocorrelation was taken as the basis of the analysis of scale effects on ecological resilience, and the generation and characteristics of ecological resilience are described. The extent effects means impact factors in different scales are different, and the spacial distributions are also different. The grain effects assume that it has a specific grain size in a certain extent. In this grain size, the spatial heterogeneity and spatial autocorrelation are expressed very well.（3）Based on the theory of ecological resilience scale effects, the method about analysis of ecological resilience scale effects were built. Firstly, the indicators which has enough spatial variability should be chosen as the initial index set of ecological resilience evaluation. Secondly, appropriate evaluation grain is determined through semivariogram granularity. At last, the final index set of ecological resilience evaluation is identified in which indicators have good spatial structures. With the evaluaion of ecological resilience, the key factors are finded in different extent, and their spatial distributions are in exhibition.（4）In this study, Hulun Buir City, forest area in Hulun Buir City and Dong Autonomous County were chose as three different research extents. The theory and methods were used in these three extents. The indicator scale effects and the eclogical resilience scale effects are both being studied. The result shows that, appropriate evaluation grains in three extents are 50km, 50km and 20km respectively. The evaluation under the appropriate evaluation grains was carried out, and the results of the ecological resilience were ranked. The nesting zones has also been recognized, which could be the essential of the protection goals.
