查询词典 population explosion

In this paper, the case study- the spatialization of China's population at the county level in the country scale can, on one side, obtain the population density of all kinds of terrain features across China. On the other side, the population density data at the county level can be integrated with environment data and social-economic data to generate 1-km grid data sets of average population density, average capacity of natural resources and others derived from environment data. And these data could be useful to monitor China's resource management, population dynamics and so on. The example study has demonstrated a plausible method of wisely using discrete point data to carry out some practical studies.

本文通过全国县级行政单位人口数据的空间化过程，一方面可以重新得到各种类型区人口居住密度的预设值或经验值；另一方面，可以将空间化后的人口数据与其他自然资源、环境数据和社会经济等数据进行有效的融合，将能得到1km格网的人均自然资源占有量、人口密度以及其他经济、环境指标的派生数据信息，这对于我们国家的自然资源管理和宏观调控、人口的动态监测等，均具有重要的实际意义。

As part of the study of social administration of Nanjing in the Republic of China, the thesis consists of 7 chapters: Chapter one explains the basic concepts of social administration and the development of modernization of Nanjing before 1927. It stresses the importance of social administration in city development through the depiction of social characteristics and problems of Nanjing. Chapter 2 introduced the theory of social administration of the Republic of China, under which the municipal institutions are structured. It focuses on the social theory of Sun Yat-sen and correlative comments of Jiang Kai-shi, which reflect the theoretic level and subjective intention of social reform of the Republic of China. Chapter 3 discusses the local autonomy of Nanjing of the Republic of China. The origin of democratic local autonomy theory and its influence over social administration are expatriated. The advantages and disadvantages of local autonomy are analyzed in detail. Chapter 4 focuses its discussion upon social rescue work, an important part of social administration, with general description of social rescue work in Nanjing and concludes the characteristics of social rescue work in the transition from the traditional to the modern society. Focusing on the prominent problem of the large flows and inflation of population of Nanjing, chapter 5 discusses the population and population management of Nanjing and outlines the population situation through analysis of the population problem, management methods and the current situation. Chapter 6 describes the unprecedentedly active citizen organizations and parties. The transform and changes of these organizations occurring under the new circumstances and their functions in social administration are analyzed to reveal the interactive function between government and social organizations in social administration. Chapter 7, the epilogue, makes theoretic evaluation of the characteristics of social administration and its revelation to the current society of Nanjing, hoping this research serves as a reference to the current time.
