地理学

This paper is a preliminary attempt to analyse the general situation of Australian geography, summarize the important scientific achievements of Australian geographers in every subdiscipline of physical geography and human geography, and introduce the theories and methods in geographical research.

本文根据七十年代以来澳大利亚地理学家的一些论著，分析了这个时期澳大利亚地理学的研究概况，探求了自然地理、人文地理的各个分支学科的主要科研成果及其实践价值，着重介绍了地学研究中的理论和方法，提出了我国地理研究中应借鉴的方面。

Modern approach methods of geography, ecology, quantitative analysis, expert integration, remote sensing image analysis and geographical information system were combined to reveal the matters in this paper. The eco-geographical background of the research area and the research work studied by other scholars were comprehensively expatiated. The temporal and spatial variation of precipitation and soil moisture, vegetation and soil distribution, and land use/land cover were compared as well. On the basis of foregoing analysis, the eco-geographical differentiation was discussed. According to principles and indicators, with extension engineering method and integrated analysis, the physical geography boundary between subhumid and semiarid areas were demarcated. By using remote sensing image analysis, wavelet analysis of the perennial precipitation and temperature, and the comparison of temporal and spatial variation of the desertification, this paper accounted for the regional response to global environmental change and suggested the dominant environmental problems.

本文采用了地理学与生态学相结合、定量分析与专家集成相结合、遥感图像解译和地理信息系统相结合的方法，对研究区的生态地理背景和已有研究工作进展情况给予了全面的分析和阐述；通过对区域水分条件（大气降水、土壤水分条件）、植被、土壤、土地利用／土地覆被状况等环境要素的时间与空间特征的对比分析，探讨了研究区内部生态地理特征的差异；在一定的原则指导下，通过建立指标体系，以可拓工程方法和模型为支撑，经过综合分析确定了研究区内半湿润、半干旱区界线划分方案；通过遥感图像解译、典型站点多年降水与温度的小波分析、土地沙漠化时空变化的对比分析等，说明了研究区域对全球变化的响应；表明了该区域所面临的主要环境问题。

Resolving the higher-level relationships among ostariophysan and related fishes will aid in resolving basal teleostean divergence and provide basis to historical biogeographic analysis of major freshwater fish groups.

解决骨鳔鱼类及其相关类群的高阶系统发育关系有助于解决基部真骨鱼的分化，而且为主要的淡水类群——世界性分布的耳鳔系鱼类的历史生物地理学分析奠定基础。

Software and results were saved in EXCEL for consequent statistic operation and obtaining chromosome patterns. 4 indexes were chose, such as chromosome karyotype, C-band pattern, chromosome behavior and B chromosome for comparative analyses, and adopted SPSS to reconstruct dendrogram. Combined with studies on insect morphology and insect geography, we made a detailed analysis and speculation on the relationship of taxa concerned. Finally we got the conclusions as follows: 1. The number of chromosomes in grasshoppers of Oedipodiae is 2n 〓=23=22+XO. All chromosomes are telocentric chromosomes. Most of the genome formulas are 3L+6M+2S+X and 3

论文选取染色体核型、C-带带型、染色体行为和B染色体这4个方面的指标进行比较分析，运用SPSS系统分析软件建立表达各属和各种之间亲缘关系的系统树，并结合昆虫形态学和昆虫地理学等方面的研究成果，对其亲缘关系进行了比较详细的分析和推测，得出以下结论：一、斑翅蝗科蝗虫的染色体数目都稳定在2n〓=23条，性别决定机制是XO型，染色体均为端部着丝粒，染色体组式以3L+6M+2S+X和3L+7M+1S+X这两种类型为主，即3对大型染色体，6～7对中型染色体和2～3对小型染色体，X染色体以中型为主，在染色体组中主要排列为4～7位。
