With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.

在语法结构方面,首先阐述了法位和法素在语法结构词法和句法中的地位和作用,以及Chomsky生成转换语法的核心内容;详细介绍了地理信息系统空间关系理论及现有的研究成果;在分析现有的拓扑关系和量度关系对空间信息结构描述能力不足的基础上,提出了基于长度比和角度差两个不变量的组合定性几何,以此建立了介于拓扑及量度约束之间的组合定性关系体系,并以此为基础派生出平行、垂直、共线、次序、直接邻近等空间关系描述;本文基于扩展的空间关系理论,详细讨论了空间关系在语音、语法和语义三个方面的语言变体,将纯几何和纯形式化的空间关系与具体的地理本体结合起来,可以获得更为丰富的、更能反映空间关系在不同语言上下文中具体体现的组合关系;最后给出了一个空间信息的语法结构的基本框架。

Climatic gradients were based on data sets from 841 meteorological stations throughout China. Definitions for floristic distributional patterns were based upon the work of Prof. Z. Y. Wu. Most of these floristic distributional patterns were strongly correlated with the geographic gradients in climate, except for cosmopolitan, cultivated and invasive genera. Tropical genera form a large fraction of the total genera (ranging from 0.84% to 94.38% in the regional floras) with the highest proportion in southern Yunnan and Hainan Island. Tropical genera occur predominantly in southern China of 0° N latitude and decreased with increasing latitude, as would be expected. Interestingly, the disjunct Tropical Asia and Tropical America distribution were not restricted to southern latitudes. Temperate genera account for 5.1% to 98.83% of the total genera in regional floras with the highest proportion in the province of Xinjiang. Most of these genera followed geographic gradients in climate as expected (temperate genera conspicuously dominate the landscape at higher latitudes), except the East Asian and North American disjunct distribution, Eastern Asian distribution and Chinese endemic distribution. Generally, most plant genera demonstrated some correlation with climatic and geographic gradients. The most important gradients were those of annual air temperature and precipitation. A small fraction did not demonstrate significantly particular pattern:"Cosmopolitan","East Asian and North American disjunct","Eastern Asian" and "Chinese endemic" distributions. The North Temperate distribution had the highest correlation with mean annual air temperature and precipitation.

结果如下:(1)除世界分布、栽培和入侵成分外,大部分中国种子植物属的地理成分的分布与地理相关密切;(2)热带分布属(泛热带分布、热带亚洲至热带美洲间断分布、旧世界热带分布、热带亚洲至热带大洋洲分布、热带亚洲至热带非洲分布及热带亚洲分布合计)占各地方植物区系的0.84%到94.38%,其最低值出现在中国西北部的新疆和青海地区,最高值出现在中国云南南部和海南;(3)热带分布属在<北纬30°的地区占优势,除热带亚洲至热带美洲间断分布外,其它热带成分随纬度增加迅速减少;(4)温带分布属(北温带分布、东亚和北美间断分布、旧世界温带分布、温带亚洲分布、地中海区、西亚到中亚分布、中亚分布和东亚分布合计)占各地方植物区系的5.1%至98.83%,其最高值出现在中国西北部的新疆地区,最低值出现在中国云南南部和海南;(5)除东亚和北美间断分布、东亚分布和中国特有分布外,其它温带成分随纬度增加迅速增加;(6)在温带成分中,东亚和北美间断分布及东亚分布属主要出现在中国亚热带到暖温带地区,北温带分布、旧世界温带分布和温带亚洲分布属在中国北部占优势,而地中海区、西亚到中亚分布和中亚分布属则在中国西北部占优势;(7)除世界分布、东亚和北美间断分布、东亚分布和中国特有分布外,所有其他成分都显示了与气候因素密切相关,其中,北温带分布属与年均温和年降雨量最为密切相关。
