Shaanxi Province For 50 Years The Amount Of Cultivated Land Change And Its Driving Force Study

Land is vital for a nation and it's people, it is not only important for the peasants, but also the resources of the people's clothing and food, therefore, it is fundamental for people to maintain a certain number of the land for their living and development, but the use of the land is effected by not only natural factors ,but also many man-made factors, that is land's economy and social environments, it includes population, agriculture, industry, communication, town's construction, culture and education, science and technology and so on, it is both the reflection of the actuality of the land's exploitation and utilize and an important factor that influences the land resources, In some way, it prescribes and restricts the land resource's exploitation and utilize and decides the land resource's using benefit. Along with the development of the economy, the construction land enlarged enormously, the Cultivated Land decreases, and the situation of the Cultivated Land protection is austere day by day, together with our country's situation that we have more people but less land, all these makes the study of the region land use transformation and it's forces to be a hotspot, Through which, we can know the natural and social forces in the land resource management clearly, such it can offer guidance for the behave of the people's using land and for the government's decision-making, and offer a theory guidance for the land's reasonable using.In this thesis, we set the Shannxi province's cultivated land as object, according to the Shaanxi province's related statistical and social economic materials, it analyzed the quantitative change of the Cultivated land resource in recent 50 years, and analyzed the factors that effected the quantity of the Cultivated land, then it made use of the science of statistics, setting the data from 1952 to 1998 as the sample and selecting 8 factors that is population, GDP, gross industry product, foodstuff's yield for a unit area, gross power of the agriculture mechanism, passenger transport capacity, resident's consumption level, gross agriculture product, because long-time data usually cover up the drive factors' specialty in different time segment ,the thesis used the method of the clustering, made time clustering for the Shannxi province's Cultivated Land change, studied the cultivated land's driving force in different time,made use of statistical software package SPSS and the method of the factor analysis to calculate the correlation matrix of driving forces variables of cultivated land changes confirmed the elements of the driving force in different time segment that effects the Shannxi province's Cultivated Land 's dynamic change process and selected the driving factors, confirming the force mechanism that effects the Shannxi province's Cultivated Land 's dynamic change process. Based on the above-mentioned, aiming at tthe conflict between the people and the land of the current and the future, the thesis put forward the countermeasure of protecting Shannxi province's Cultivated landreasonably.
