Based on a series of analysis for the relevant data during the period of 1950~1989, the relationship between the ozone layer variation/ solar activity and the periodically prevalent features of two kinds of human infectious diseases in China, the epidemic cerebrospinal meningitis and human plagueepisodes, is presented and analyzed for the first time in this paper.

通过对1950~1989年间一系列有关资料进行分析，首次研究和报道了臭氧层变化、太阳活动与流行性脑脊髓膜炎及鼠疫传染病发病率流行周期特征之间的关系。结果表明，从较长时段看，臭氧层变化、太阳活动与ECM、HP年发病率间存在着较为密切的相关关系；从较短时段看，发病率的季节变化与某些气象因子的变化有一定的关系。此外，本文还提出了一个解释这两类疾病周期流行机制的简单模型

And further on corporate social responsibility and economic performance test of the relationship between the weak negative correlation between the presence, but the difference was not significant, not inference overall, but at least that corporate social responsibility will have a little to do with its economic performance.

并进一步对企业社会责任与其经济绩效的关系进行检验，两者存在弱负相关关系，但差异不显著，不能推论总体，但至少说明企业承担社会责任的好坏与其经济绩效关系不大。

Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.

分析近50年气候资料和人文因子在不同年代的变化特点，系统地研究了气温和降水等自然因子和人口、农牧业发展、经济状况等人文因子对区域土地利用变化的影响；从时间序列的角度分析了50年代至80年代初和80年代中期至2000年两个时段土地利用／土地覆被变化的驱动因子，在相关分析的基础上，分时段建立了区域土地利用／覆被变化的自然-人文影响统计诊断模型；针对不同经济类型区选择典型县，分析近15年土地利用变化外在人文驱动力的区域相似性和差异性；尝试以THIESSEN多边形方法进行社会经济统计数据的空间化处理，探讨了土地利用程度变化与人文因素变化的空间相关关系；以优先指数模型和土地利用类型转化率与距交通干线距离的相关模型分析了景观自然与人文结构对土地利用空间转化过程的影响。

This paper explains the complicity of nationalism and literary history by reexamining the relationship between Liang Qichao's nationalism and the appraisal of Lu You, and also by tracing back that appraisal. Thus we need to find was to describe the correlation of society and the history of Chinese literature as the history of East Asian literature.

本文试图重新考察梁启超的国家主义与陆游评价的关系，追溯陆游评价的系谱，从而解析国家主义与文学史之间的「同案犯」的关系，并由此摸索如何从东亚文学史的角度、在与社会的相关关系中来叙述中国文学的历史。

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.

结果表明：（1）氮素添加提高了土壤中NO3—- N等可利用资源的含量，增加了植物群落植被的盖度，减小了植被的透光率，随着施氮量的增加群落中物种丰富度显著降低（P 0.001）；（2）氮素添加显著改变了植物群落地上生产力（P 0.05），随着施氮量的增加地上生产力呈现先增加后降低的变化趋势，各功能群中禾草生物量显著增加，而杂草和豆科生物量随施氮量增加逐渐减少；（3）物种多样性与植被透光率呈线性正相关（P 0.05）；地上生产力与土壤NO3—- N含量呈线性正相关（P 0.05）；随着施氮量的增加物种丰富度与生产力之间呈负相关关系。

The shrinkages in tangential and longitudinal directions were negatively and positively,respectively,correlated with GS/GSI,while no clear relation was found between radial shrinkage and GS/GSI.

无论是正常木还是应拉木，在组织和宏观水平上(分别基于切片和实木上的观测)，弦向的干缩率都明显高于径向的，弦向和轴向干缩率分别与GS/GSI呈显著的负相关和正相关，而径向干缩率则与GS/GSI之间没有发现明显相关关系。
