“高分一号”卫星数据遥感影像分类方法研究——以内蒙古维拉斯托地区为例

"高分一号"(GF-1)卫星是中国高分辨率对地观测系统的首发星,突破了高空间分辨率、多光谱与宽覆盖相结合的光学遥感等关键技术,开启了中国对地观测的新时代。文章以内蒙古维拉斯托地区为研究对象,首先对GF-1卫星采集的遥感数据进行正射校正、配准、融合、裁剪等预处理;采取不同的图像分类方法提取研究区地形地貌特征及矿业活动特征,并对不同分类方法提取结果进行合并处理与精度评价。结果显示,利用监督分类中人工神经网络方法可以对研究区中的矿业活动特征进行有效的提取。同时应用此种分类方法对大兴安岭西区景观特征的提取也有指导意义。     

基于“六普”与“七普”数据的中部五省人口变化特征与规划应对

文章基于“六普”与“七普”数据的对比,分析2010～2020年中部五省的人口变化规律。研究结果显示,中部五省(除河南省外)10年来人口呈正增长的地级市通常不超过6个,中部五省在“强省会”战略下,人口进一步向省会城市及都市圈近域集聚态势显著,省会城市与次中心城市的人口增量悬殊拉大,大量城市呈人口负增长态势。根据研究结果,文章提出在国土空间规划编制过程中,需夯实“七普”数据研究的基础性作用,加强人口—经济—用地—资源的适配性研究,结合“强省会”战略下人口负增长城市的成因,精准判定收缩城市的类型及提出国土空间规划应对建议;需依托人口集聚特点、增长动力及空间分布,对省会城市、次中心城市和地级市进行差异的城镇化模式引导。     

“熵”定律在信息设计中的应用

"熵"的概念起源于大自然,是表示变化方向非常重要的物理量,一个系统的熵值描述了它所处状态的混沌程度:熵值越大,系统状态越混乱。如今熵定律已经远远超出热力学的范畴,在信息设计这一多种新兴学科交叉的领域里,它是一个描述设计对象的混乱程度的度量。本文引用熵定律,对信息设计中的信息图形创意、信息整理和信息降噪进行分析,并探讨了如何用熵减的设计观来指导信息设计,让信息设计达到更加高效的交流目的。

Investigation of attitudes towards the effects of land use change using image editing and Q sort method

Image capture and editing techniques were combined with the Q sort method to investigate public preferences for the effects of proposed changes to land use in the New Zealand high country. Stakeholders expressed preferences for information cards that presented the effects of a range of land use options, including forestry, agriculture and conservation. Several indicators of environmental effects for each land use option were presented, including the predicted visual effects of both the land use and its consequential impacts such as wilding spread, and estimates of non-visual socio-economic and environmental effects such as changes in local farm income and employment, and in soil status. Seventy-seven stakeholders assessed a total of 36 options covering four land forms. Analysis of results has identified several clear ‘themes’, or sets of preferences for a distinctive set of land use options and distinctive combinations of effects. Results were integrated into a comprehensive decision support system that provides information on socio-economic effects of land use change. The method was successful in integrating stakeholder preference into resource planning for a complex set of potential environmental effects, but some problems have been identified, and these are discussed.     

Developing and testing a cost-effectiveness analysis to prioritize green infrastructure alternatives for climate change adaptation

Green infrastructure has been increasingly identified as an option to help manage climate change impacts in urban areas, although its implementation is still not widely promoted in urban planning. This is because of the lack of detailed analysis for decision-makers regarding construction and maintenance costs for different types and how effective various measures are at managing precipitation at a catchment scale. This paper contributes to fill this gap in knowledge by developing a green infrastructure cost-effectiveness ranking index (GICRI) able to evaluate the stormwater runoff volume reduction of multiple green infrastructure alternatives under different climate change scenarios, over differing spatial configurations and combining this performance data with their construction and maintenance costs. After applying this model over two case study areas, this paper provides three main insights. First, climate change projections have a significant impact on green infrastructure cost-effectiveness. Second, as green infrastructure cost-effectiveness is influenced by the spatial scale, there are different challenges for larger cities and smaller regional towns. Building on this, the paper argues that GICRI can be a simple and fast heuristic to increase the use of green infrastructure by informing decision-makers regarding how and where to prioritize investment or where greater modelling is needed.
