Abstract： [Purpose/Significance] "People-centered" is the basic principle of the construction of rural public cultural service system in the new period and the important criterion of efficiency evaluation. During the "14th Five-Year Plan" period, with the continuous improvement of the rural public cultural service system framework and the continuous increase of the total supply, the relevant policies of rural public cultural services have begun to move toward the era of "high-quality", "high level" and "high quality" efficiency improvement. [Method/Process] Based on the policy and demand orientation, this paper constructed the evaluation index system of rural public cultural service effectiveness, and designed 17 specific indicators from 5 dimensions, such as awareness, participation, satisfaction, sense of cultural acquisition, and cultural happiness, and takes the Beijing ecological conservation area as a typical example to carry out the "people-centered" efficiency evaluation of rural public cultural service. [Results/Conclusions] At present, the average score of rural public cultural service efficiency in Beijing's ecological conservation area is 75.90 points, which is in the "medium" level, indicating that the overall efficiency level of rural public cultural service in Beijing's ecological conservation area still has a large room for improvement. The participation score is the lowest, and there is a large difference in the participation level and the sense of cultural acquisition level among groups, indicating that the efficiency level of rural public cultural services has a large room for improvement, and the construction is unbalanced. The ultimate goal of improving the efficiency of rural public cultural services guided by "people-oriented" is to build a rural public cultural service system with everyone's participation and shared by all, meet the new expectations of rural residents for a better spiritual and cultural life, and make public cultural services play a greater role in promoting the comprehensive revitalization of rural areas. In the future, it is necessary to optimize the structure and layout of public cultural service facilities, promote the transformation of public cultural service products from universal to precise, build a multi-level and multi-channel public cultural supply mechanism, and deeply explore and innovate the excellent traditional local culture, so as to improve the efficiency level of rural public cultural services.

Abstract：人为践踏对湿地苔藓地被的影响一直不清楚。以采自长白山区月亮湾湿地开阔地的红型和林缘的黄绿型中位泥炭藓（Sphagnum magellanicum）为实验材料，室内模拟人为践踏，使用便携式调制叶绿素荧光仪，测定其叶绿素荧光参数，研究不同践踏强度、不同践踏轮次下，两类中位泥炭藓的荧光参数响应情况。结果显示：践踏第二轮，红型中位泥炭藓的PSII实际光量子产量[Y（II）]和相对电子传递速率（ETR）随践踏强度增大而减小，而黄绿型的践踏组均大于对照组；践踏结束时，红型的Y（II）和ETR的践踏组均显著低于对照组，而黄绿型只有轻度践踏低于对照组；黄绿型泥炭藓践踏组的非调节性能量耗散量子产量[Y（NO）]甚至要低于对照组。研究表明，尽管泥炭藓属植物能耐受一定的践踏胁迫，但随着践踏轮次增多、强度增大，胁迫累积效应将强烈抑制其生长；多见于开阔地的红型泥炭藓对人为践踏的耐受能力低于林缘生境的黄绿型泥炭藓。湿地保护与管理中，应减少游人践踏干扰，尤其要严格控制开阔地生境的游人进入。
