在推动生态文明建设，落实资源环境保护的进程中，自下而上的社会反馈是否发挥作用，地方政府如何回应民众环保诉求备受关注。研究基于2011—2020年中国30个省面板数据，实证探讨环境社会反馈对区域污染排放的影响，并建构“信号—约束—回应”模型进一步考察地方政府面对环境社会反馈何以呈现差异化回应策略。研究发现，各地区污染物排放呈逐年下降趋势，其中社会反馈与区域污染排放呈负相关关系，即关于环境问题的社会反馈能够释放某种信号和压力引起政府回应。对社会反馈与治理任务细分发现，地方政府在回应环境社会反馈时，在回应对象上偏好信号效应突出的强信号社会反馈，在回应内容上偏好绩效特征突出的显性绩效任务。进一步分析发现，由于注意力资源的稀缺性以及由此产生的注意力竞争和分配，地方政府经过恰当调适后做出差序回应的理性选择。研究认为，为提升环境治理绩效，地方政府应进一步平衡对不同类型社会反馈的回应力度，平衡显性绩效与隐性绩效任务治理，发挥环境社会参与和政府环境规制的协调效应。研究为理解环境治理视阈下社会反馈绩效和政府回应形式提供了重要参考，对中国环境治理体制研究亦有一定贡献。

Chinese Journal of Aeronautics 2018年第10期31卷 2023-2033页

作者： Hongliang LI Dong LI Yunhua LI School of Automation Science and Electrical Engineering Beihang University Beijing Aeronautical Science and Technology Research Institute of COMAC School of Aeronautic Science and Engineering Beihang University

This paper deals with the multi-index assessment method for evaluating coverage effectiveness of remote sensing satellite. Because a series of satellite activities such as imaging, moving target observation, and environment investigation need to know the coverage characteristics, the coverage capability of the remote sensing satellite is the most important index. Thus, it is very important to establish the method of effectiveness evaluation of coverage characteristics. This paper focuses on the assessment of coverage effectiveness of remote sensing satellite, and proposes and designs a multi-index evaluation method based on index weight using entropy weight method and analytic hierarchy process. With a simulation case, the effectiveness evaluation results of single satellite coverage and multi-satellite coverage performance are given for the proposed *** experimental results show that the established coverage characteristic model and the proposed assessment method are effective and right.

Greenway is a green linear corridor connecting scenic spots, residential areas, nature reserves, road traffic, etc. Rational greenway route selection can not only attract tourists to increase the income of local villages, but also arouse people’s awareness of the protection of traditional villages. This paper took Xingtai County, Hebei Province, China as an example to practice greenway route selection in the county territory. Eight factors were selected for greenway route planning, namely elevation, water body, mountain, ecological protection redline, cultural relics protection units, population density, road traffic network, and important transportation hub. These eight factors were assigned in the GIS platform, and the suitability evaluation system of each factor was constructed. The analytic hierarchy process (AHP) and entropy weight method were combined to calculate the weight of these eight factors. The raster calculator was used to weight and overlay the suitability evaluation system of each factor, and the comprehensive suitability evaluation map of greenway route selection was obtained. Based on an important transport hub, along with the water body and the road traffic, the final selection greenway route of traditional villages in Xingtai county was formed. The results of the research can provide a certain reference for the greenway route selection at the county scale.
