RS and GIS-based Analysis on Dynamic Changes of Landscape Pattern on Urban-rural Fringe——A Case Study of Licheng District, Jinan City of China

By using GIS, RS and landscape ecology, LandsatTM (1993 and 2009) and ETM (2001) remote sensing images of Licheng District of Ji’nan City, Shandong Province were interpreted, and dynamic changes of landscape pattern in the district were analyzed at the levels of class and landscape. The results showed that during the 16 years the landscape pattern in the district had changed significantly. (a) From the perspective of patch category, areas of arable land, woodland and grassland decreased unceasingly, and arable land accounted for the largest reduction from 488.15 km 2 in 1993 down to 324.37 km 2 in 2009, witnessing a reduction rate of 33.56%. But the patch quantity and fragmentation increased, patch connectivity reduced. Spatial pattern of construction land expanded and its area witnessed a significant increase of 147.05%. Patch cohesion index increased and connectivity grew better. (b) From the perspective of overall landscape, patch quantity, contagion and perimeter-area fractal dimension decreased, patch shape became simple, the Shannon’s diversity index, Shannon’s evenness index and splitting index increased, landscape heterogeneity rose. With the rapid social and economic development, landscape pattern will be more and more influenced by human behaviors

Comparative Analysis on Observation Data of the Transfer Station in Nanning National Weather Station

[Objective] The research aimed to analyze difference of the observation data by transfer station in Nanning National Weather Station. [Method] By using observation data (atmospheric pressure, temperature, relative humidity, wind direction and speed, precipitation, sunshine, etc.) from January to December in 2000 at old and new Nanning National Weather Station, difference of the each meteorological factor was contrasted. Main reason for difference of the each meteorological factor was analyzed from altitude, underlying surface property and station environment. [Result] Atmospheric pressure and temperature at new station were both lower than that at old station, while relative humidity and wind speed were both higher than that at old station. Rainfall and sunshine had big differences at new and old stations, but variation did not have rule. Main reasons for obvious difference of the meteorological factor were that altitude, observation environment, terrain and underlying surface property at new and old stations were different. Influences of the altitude and observation environment were especially significant. [Conclusion] The research provided basis for continuity and homogeneity correction of the data sequence at Nanning National Weather Station.

Temporal and spatial pattern of land use change in Ji’nan since the late 1980s

Taking Ji’nan as a case study area,this paper aims to analyze the land use changes from late 1980s to 2010 by using remote sensing data.The geographic information systems(GIS)method and land use transfer matrix methods were used to calculate the temporal and spatial differences of land use change.From the analysis of the land use transfer matrix,the most significant change is the cultivated land being transferred to construction land.From late 1980s to 2010,a total of 20615 hectares of cultivated land had been converted to construction land,accounting for 11.04%of the cultivated land in all.Through the analysis of the factors of land use transition,the human dimensions that had influenced the land use changes were population factor and economy factor.

湖北荆州张大冢战国楚墓出土青铜器的成分与金相研究

利用X射线荧光光谱仪(XRF)、金相显微镜对荆州市纪南镇雨台村张大冢战国墓地出土12件青铜器进行成分与金相分析。结果表明,12件青铜器分别为铅锡青铜、锡铅青铜和锡青铜3种材质,铅锡(或锡铅)青铜器普遍含铅量较高,青铜器多以铸造成形,铜盘均采用热锻加工技术。不同类型及使用功能的器物,其合金成分与金相组织存在明显差异。张大冢墓地作为战国中晚期的楚国下等级贵族家族墓地,出土青铜容器也多为素面薄壁,锈蚀较为严重,但其出土青铜器的合金配比、制作技术及机械性能均展现出战国中晚期楚国工匠已经拥有成熟的青铜合金、铸造以及加工技术,也揭示出当时工匠有意识地在青铜明器与实用器的合金技术上存在区别对待,为全面认识东周时期楚都纪南城青铜冶铸业的发展状况提供科学依据。

虚构的诗文唱和——《谦斋南渡集》所载策彦周良与明朝君臣的唱和诗

据《谦斋南渡集》记载,策彦周良在出使期间曾与明朝君臣进行诗文唱和。但考察《策彦和尚入明记》等相关文献可知,诗文唱和的时间、地点、参与人物、诗文内容等信息均存在与事实不符之处。此外,考虑到嘉靖皇帝对日本极为不满的态度,同时期来华朝贡的朝鲜使节亦未曾享有与明朝君臣诗文唱和的殊荣,以及《谦斋南渡集》中也存在其他虚构现象等因素,可以确定书中所载策彦周良与明朝君臣进行诗文唱和之事应并未发生。该场景应是策彦周良或其门人的虚构。这种在华经历的虚构应与日本由来已久的“慕华”思想、有先例可循的虚构现象以及由此带来的现实利益等因素相关。

近50年济南岩溶泉域地下水位对降水响应的时滞差异

依据近50年降水及年均水位等的差异，将1959-2011年济南岩溶泉域地下水位与降水观测数据划分为若干时段。采用小波变换方法定量分析了泉域地下水位对降水的响应时滞，并采用相关分析讨论了时滞与地下水开采量等的关系。结果表明，（1）泉域地下水位与降水的主周期均为1a。（2）两种划分方式下，泉域排泄区水位时滞分别为83．44～161．24d、88．62~150．56d，径流区水位时滞分别为67．87～81．66d、76．58～82.21d，径流区水位时滞明显小于排泄区。（3）依据降水划分的时段，排泄区与径流区均有随年降水减少。水位时滞增加的趋势。（4）依据水位划分的时段，排泄区有随水位降低，时滞增加的趋势，而径流区不明显。（5）泉域水位时滞与泉域地下水开采量、泉群流量等存在相关关系，泉域开采量越大，泉群流量越小，则水位时滞相对越大。上述时滞差异分析，有助于增加地下水位与降水之间的非线性耦合过程的认识，可为地下水位的预报预警提供帮助。

济南市环境空气VOCs污染特征及来源识别

对济南市2010年6月至2012年5月环境空气中56种挥发性有机污染物（VOCs）进行在线气相色谱监测,研究其污染特征并识别其主要来源。结果表明,该期间总挥发性有机化合物（TVOCs）变化规律基本一致,其平均浓度水平夏季〉冬季〉秋季〉春季;TVOCs浓度的日变化趋势呈双峰分布,与早晚交通高峰相吻合;济南市城区环境空气中VOCs的主要物种是C3~C5的烷烃、丙烯、顺-2-丁烯、甲苯和间、对二甲苯等;不同季节环境空气中VOCs的主要物种基本一致,夏季烯烃所占比重高于其他季节;烷烃、烯烃与TVOCs的浓度日变化趋势相似,呈明显的双峰状,而芳香烃浓度日变化规律双峰特征不明显。济南市城区VOCs的主要来源为汽车尾气、工业源、燃烧源。

高铁开通前后站区产业空间格局变动及驱动机制——以沪宁城际南京站为例

基于企业微观数据,定量刻画高铁开通前后站区产业空间格局变动,并诊断和确定在不同阶段的关键驱动要素及其贡献度。结果表明,高铁站区产业空间具有明显的圈层结构,但"以高铁站点为中心的向心集聚"在高铁开通初始阶段尚不明显,开发强度并不随着与站点距离增加而降低,核心区的开发强度小于影响区。除了圈层空间分异之外,产业分层集聚态势凸显,与高铁乘客的商务特征相对应的商务服务业在高铁开通后空间集聚程度明显高于其他几类产业;批发零售业、居民服务业和科技服务业与高铁开通相关性不明显;交通运输业和住宿餐饮业作为交通站区的基础服务产业,相关程度介于以上两类之间。从内外两方面驱动因素构建的高铁站区产业空间格局变动模型分析得出,除了交通条件、外部规模经济等传统区位因素外,产业属性、地价对高铁站区产业空间格局的变动有较大影响。

济南市农村居民点用地整理潜力

研究目的:分析农村居民点整理潜力实现的可行性,有效评估农村居民点整理潜力及增加耕地潜力。研究方法:以济南市为例,选取地形、社会经济因素以及土地资源和宅基地利用等11个因素,构建农村居民点整理潜力修正指标体系,将农村居民点整理的理论潜力修正为现实潜力,并根据土地适宜性评价,估算增加耕地潜力。研究结果:济南市农村居民点整理潜力修正系数平均为0.43,理论潜力转化为现实潜力的可行性较差,全市农村居民点整理增加耕地系数平均为25.76%,且北部平原区农村居民点整理潜力大于中南部低山丘陵区。研究结论:(1)农村居民点整理理论潜力转化为现实潜力的可行性受自然条件、社会基础、经济实力和土地资源利用状况的制约;(2)受自然限制性因素制约,农村居民点并不都适宜整理成耕地,应该因地制宜地对农村居民点采用多样的开发利用方式。

京沪高速铁路济南西站复合地基施工期的沉降分析

在软土地基修建高速铁路和客运专线时,对软土地基进行沉降观测,对于保证工程质量和工期具有重要的意义。选取京沪高速铁路济南西站DIK418+298.9断面进行沉降监测,分析堆载预压的填筑高度对复合地基的影响。试验结果表明:在填筑过程中,地基沉降量随预压土填筑高度的增加而增加;在预压过程中,复合地基沉降量先急剧增大,后趋于稳定;卸载预压土后,复合地基的沉降会有一定量的回弹。
