Quantification and localization of the intensity are the key points for evaluating the impact of human activities on coastal wetland environment. A Human Activity Intensity Index (HAII) and a spatial simulation method were presented based on the resilience of nine landscape types to human activities, the attenuation and combined effects of different landscape types and the different ecological conditions within the same landscape type. To verify the accuracy and suitability of the method, the coastal wetlands of Laizhou Bay were chosen as the study area with four period (1990–2016) GIS data and seven representative stations field survey. The change of landscape patterns, characteristics of landscape heterogeneity, and human activity intensity in Laizhou Bay were analyzed. The results showed that: the number of patches (NP) increased 129% in the study area during 1990–2016. The change in the landscape pattern was essentially consistent with changes in human disturbance intensity and urban expansion. Construction land area ratio increase from 5% to about 25%, the conversion of farmland to construction land accounted for 78% of the total growth, indicating that human activities caused by towns and ports are distributed in points that have a spatial aggregation effect, which causes the increase of complexity and heterogeneity of landscape patches. The HAII is represented by rapidly increase from points to surface, indicating that the method constructed in this study clearly reflected the trend. The landscape of salt fields and cultured ponds were distributed in sheet distribution, usually connected with the construction land, so did the combined effects at the edge. Therefore, the proposed HAII calculation and spatial simulation method reflected the attenuation and combined effect can be used in the evaluation of human activity intensity in coastal areas.

强度的量化和定位是评价人类活动对滨海湿地环境影响的关键。基于9种景观类型对人类活动的恢复力、不同景观类型的衰减和组合效应以及同一景观类型内的不同生态条件，提出了人类活动强度指数（HAII）和空间模拟方法。为验证该方法的准确性和适用性，选取莱州湾滨海湿地为研究区，利用4个时期（1990-2016年）GIS数据和7个代表性站点进行实地调查。分析了莱州湾景观格局变化、景观异质性特征及人类活动强度。结果表明：1990-2016 年期间，研究区的斑块 (NP) 数量增加了 129%。景观格局的变化与人为干扰强度和城市扩张的变化基本一致。建设用地面积比例从5%提高到25%左右，农用地转建设用地占总增长的78%，说明城镇和港口引起的人类活动呈点状分布，具有空间集聚效应。导致景观斑块的复杂性和异质性增加。HAII 表现为从点到面的快速增加，表明本研究构建的方法清楚地反映了这一趋势。盐田和养殖池塘景观呈片状分布，通常与建设用地相连，边缘的综合效应也是如此。因此，所提出的反映衰减和综合效应的HAII计算和空间模拟方法可用于沿海地区人类活动强度的评价。
