Modern Translation of Classical Gardens:Landscape Design Conception and Strategy of Gaobeidian Train New Town in Longhu

This study introduced the design process and main contents of a project called Gaobeidian Train New Town in Longhu,which won the excellence award in the 55th international competition in 2018 hosted by International Federation of Landscape Architects (IFLA).In view of the separation of traditional cultural heritage and modern society and the disappearance of traditional culture,this study put forward the design concept and strategy of connecting traditional culture and modern landscape with Ziquan Palace as the design prototype by means of elastic landscape design,so as to continue the gene of traditional culture and arouse people’s awareness of respecting and protecting traditional culture.

以“树”为基础的彝族传统农作

在彝族人的观念中,自然来自于一棵"梭罗树"的变化。天上"梭罗树"产生着生命的灵魂,调控着自然万物,地上树木承载着"梭罗树"的职能,管理维护着生命的存在。在"树"自然观的指导下,树木成为农业生产的必要条件,各种树木的存在是农业生产的保障。不仅作物种子要由树木要赋予,农作物生产所需的水肥、耕作节令、病虫防治以及收获都依靠树木来调控。彝族传统农作以树木的利用为基础,农业生产不仅具有森林利用的规划,也有着树木的生产与维护。根据树木生长的规律对树木进行砍伐利用,将作物生产与树木生长相结合,彝族传统农业维护了自然的多样性。     

基于文献数据统计的中国土地整治研究现状与趋势分析

通过对中国土地整治文献进行系统梳理,客观分析我国土地整治的研究现状,明确当前的研究前沿与热点问题,为土地整治领域的土地管理决策者和科研工作者提供参考。基于CNKI文献数据库,对文献数据采用定性与定量的分类与统计方法,根据论文发表数量、期刊、研究机构、被引频次等指标,分析我国土地整治的研究现状、前沿热点、发展趋势等。结果表明:土地整治领域文献数量在20世纪80年代开始增长,到2010年之后达到高峰,不同期刊在论文发表数量和影响因子上具有一定差异性,研究机构以高等院校和土地管理部门为主,并逐步形成了土地整治研究的核心团队,随着土地整治目标转型,我国土地整治发展经历了4个阶段,土地整治研究尺度主要是宏观、中观、微观三个层次,未来土地整治技术研究应进一步加强,近期土地整治研究热点主要集中在5个方面。研究结论:中国土地整治处于转型发展期,今后应继续深化土地整治基础理论研究,重点在国土综合整治,耕地数量、质量、生态管护,地力退化土地整治,工程装备与技术四个方面加强相关研究,支撑土地整治学科发展。     

基于烤烟透射特征的烟叶图像分割研究

在专门设计的灯箱中拍摄烤烟烟叶的反射和透射图像，对这两类图像分别以3×3像素矩阵作为区域对象采样，统计比较了烟叶、背景两区域的RGB属性特征，发现透射图像烟叶区域绝大多数像素的蓝色属性等于零，少数像素的蓝色属性大于零，并在采样矩阵中呈不连续分布， 矩阵内9个像素蓝色属性的相对标准偏差(RSD)或等于零，或大于100％。研究采用该特征作为依据，对烟叶透射图像进行了区域统计法分割。结果表明分割精度高于点统计法，每片烟叶像素数平均高出0.65％，较好地保留了目标图像的原始特征信息。该研究提出的图像分割方法有利于提高分割结果的可信度，为利用烟叶透射特征进行后续研究奠定了基础。     

Regionalization of organic pollutants in Bavarian soils: The performance of Indicator Kriging

The evaluation of the impact of additional soil pollutants has to be contrasted against the naturally occurring pollutant concentration, i.e., the background concentration. Because background concentrations have to represent areal entities, point information has to be extrapolated into the area using interpolation methods. Thus, the accuracy of the interpolation method is crucial for the correct designation of background values to the areas. For the area of Bavaria (SE Germany), the actual background values of organic and inorganic soil pollutants were derived from >337,000 data from 5000 horizons based upon 1134 soil profiles. Background values were determined for the different soil depth compartments (O layer, topsoil, subsoil, and parent material) and land uses (agriculture, forestry). For interpolation between the nodes, Indicator Kriging was applied. The kriged total area was subdivided into 6 subareas of different background concentrations using percentile thresholds. To derive representative background concentrations, the reliable segregation of the total area into subareas and, thus, a robust interpolation method is a prerequisite. In this study, the robustness of the applied Indicator Kriging should be tested. Influences of data transformations and different kriging methods upon the demarcation of subareas should be investigated for the organic sum‐parameter EPA‐PAH. Neither a data transformation nor the comparison with Ordinary Kriging yielded significant deviations in the assigned subareas. Furthermore, cross‐validation as well as addition of synthetic noise was used to check the susceptibility of the method to artifacts and changes in the data set. After random splitting of the original data set into 4 subsets and re‐arrangement to 6 half‐sets, subsequent Indicator Kriging produced 6 results with mainly identical subarea configurations. Cross‐validation, i.e., comparison of points from the kriging surface (validation data set) with the calibration data set, yielded considerable residuals between estimates and measurements. Based on these normally distributed residuals, random numbers with identical statistical moments were generated and used as measurement errors for another kriging run. This synthetic noise was added to the corresponding result based on the calibration half‐set. The resulting subareas changed only slightly for the most polluted region, but considerably for the other regions. The chosen interpolation method provides sufficient stability to demarcate the relevant areas with elevated pollution in Bavaria. For other areas, its stability is less clear. Here, additional soil samples are required.
