The Driving Mechanism Of Land Use Change For Rural Residency

The study on land use/land cover change(LUCC) and its driving mechanism is one of main subjects of global change. There are a lot of governments, scientific research institutes and non-governmental organizations paying much attention to land use/land cover change around them. There are a large number of populations, but relatively limited land especially cultivated land resource in China, and the economy development and people's living standard improves fast. These peculiar national conditions make the studying of LUCC have more practical significance in our country. The broader distribution, smaller scale, larger quantity and lower price compared with urban land are the characteristics of rural residential area in our country. Because of little economy constraint, the rural residential area is spreading instead of decreasing. The rural residential area expansion becomes a greater threat to the cultivated land than the urban land, and becomes a key factor lead to the decreasing of cultivated land resource.Therefore, reinforcing the research of change and its driving mechanism of land use for rural residency is significant to protect farmland resource theoretically and practically, optimize the structure and layout of rural residential area, promote the intensive land use, move forward the construction of New Rural Areas actively, boost the surplus rural labors' transfer, and develop the urbanization. So it will become one of important aspects of LUCC study in our country. However, restricted by the data, domestic scholars pay much attention to the change of urban land use, and rural residential land use change has been ignored for a long time. Therefore, reinforcing the study on the rule and driving mechanism of rural residential land change appears especially important.Farm household is the microcosmic main body of rural residential land use. The behavior of choosing residence to build house and the decision-making of farm household affects the change of rural residential area directly. Therefore, the main purpose of this thesis is to explore the rule and driving mechanism of rural residential land change and to provide scientific reference to make proper land use policy.The research is based on questionnaire of 830 and land resource exploration data, using linear regression model and Logistic regression model to analyze the rule and microcosmic mechanism of rural residential land change in Jiangxia District of Wuhan City, Xiaonan District in Xiaogan City and Zaoyang City in Hubei province.The content of the thesis is following:In chapter 1 the background and the meaning of the research, the definition of relative concept and research conditions are expounded, the research route and content are introduced. In chapter 2 the microcosmic driving mechanism of rural residential land use change are studied. Rural residential land use change includes quantity change and intensity change. Farm household is the microcosmic main body of rural residential land use. Their behavior of choosing residence to build house affects the change of rural residential area directly. In China the society is reforming, the economy is developing rapidly, the degree of industrialization and urbanization are improving, which influences the farm household's behavior of choosing residence to build house. The characteristics of farm household's include population structure and family income and so on, also influence the behavior of choosing residence to build house, which lead to rural residential land ues changing. In this chapter we give a priority to study the microcosmic driving mechanism of rural residential land use change to provide the basis for the further empirical study.Chapter 3: The choosing of investigated regions and their characteristics of rural residential land use change. Hubei Province is located in central China, an important nationwide production base of grain. The general configuration of the earth's surface type is various, and the economic growth is unbalanced in Hubei. The dissertation selects Jiangxia District, a suburb of Wuhan City, Xiaonan District in Xiaogan City and Zaoyang City in Hubei province as the basic point of research.Chapter 4: Because of the unbalance of economic development, the rural residential land use change is different among the three districts. It is showed that to the rural residential land scale, Zaoyang City＞Jiangxia District＞Xiaonan District; while to the capability it showed that Zaoyang City＞Jiangxia District＞Xiaonan District.Chapter 5: Empirical study on driving mechanism of rural residential land change. By using SPSS 13.0(Statistical Program for Social Sciences) and investigated data of farm household, we analyze the microcosmic driving mechanism of rural residential land change by constructing linear regression model. The research results are as follows: the scale of family population, the proportion of fund when the farm household building their house, the householder's education level, the acquaintance degree to Land Administration Law etc has the remarkable influence on the area of rural housing land. But the capability of rural housing land is mainly influenced by the scale of family population, the age of householder, the male proportion of farm household, the amount of old people and children, the proportion of fund when the farm household building their house, the comprehension degree to Land Administration Law etc. By the analysis, we find that the influence is different in different research districts.Chapter 6: Analyze of the direction of the change of land use for rural residency based on farm households' willing. By using SPSS13.0, we adopt the data of 776 investigated farm households, constructing Logistic regression model to analyze their plan of building house, the attitude towards village programming and migrating to central village separately in the near future. The research results are as follows: the main factors that influence the choice of building house are the male proportion of farm household family, the amount of old people and children, the average age of labor force, average net income per capita of farm household, the years of house using and the comprehension degree to Land Administration Law etc. The main factors that affect the attitude towards village plan are average net income per capita of farm household, per capita living space of farm household and the comprehension to Land Administration Law. The main factors that affect the attitude to migrating to central village are average net income per capita of farm household, the comprehension degree to Land Administration Law and the number of typeⅡnon-agricultural income family. These factors have different effects on the rural residential change in different region, which provides scientific basis to formulate proper policy to adjust rural residential change by this studying.Chapter 7: conclusion and discussion. Summarized the primary conclusion, made some discussion to the shortage in the thesis. Based on the conclusion, we put forward some suggestions of controlling the rural residential land use scientifically.
