【摘要】： 中國把“十分珍惜、合理利用土地和切實保護耕地”作為基本國策,并實行嚴(yán)格的土地用途管制制度保護耕地。中國的耕地保護制度在強調(diào)各區(qū)域內(nèi)耕地總量動態(tài)平衡的同時忽略了不同地區(qū)耕地資源稟賦和經(jīng)濟發(fā)展水平的差異性,忽略了人口遷移、城鄉(xiāng)差距等因素變化對耕地保護外部環(huán)境帶來的不確定性。近20余年來,中國的流動人口數(shù)量空前激增,其中絕大部分是從不發(fā)達地區(qū)流向發(fā)達地區(qū)的農(nóng)村人口,這部分流動人口的兼業(yè)性質(zhì)和兩棲占地特征對各區(qū)域的耕地利用水平產(chǎn)生了一定影響,也為各地區(qū)選擇差別化的耕地保護戰(zhàn)略提供了可能。研究流動人口對流入地區(qū)和流出地區(qū)耕地利用和保護的影響,可以為制定動態(tài)的,彈性的耕地保護政策提供依據(jù),為制定合理有效的耕地保護措施提供思路。本文的研究包括三部分 首先,通過流動人口集中度、耕地資源集中度和區(qū)位熵的測算,掌握流動人口和耕地資源的地區(qū)分布和特點,并分析兩者的內(nèi)在聯(lián)系。 其次,本文在人口普查和農(nóng)業(yè)普查數(shù)據(jù)的基礎(chǔ)上,利用簡單相關(guān)性分析、曲線擬合和基于面板數(shù)據(jù)的C-D函數(shù)等計量分析方法,揭示了農(nóng)村外出從業(yè)勞動力對人口流出地區(qū)耕地經(jīng)營規(guī)模、耕地投入水平、耕地利用方式變化以及耕地糧食生產(chǎn)能力的影響。另外,本文還探索了農(nóng)村外出從業(yè)勞動力對流入地區(qū)城市化、建設(shè)用地擴張的影響以及對該區(qū)域耕地保護的間接影響。該部分研究得出四點結(jié)論： 一、人口流出地區(qū)勞動力轉(zhuǎn)移與耕地規(guī)模經(jīng)營之間經(jīng)營缺乏良性互動。 二、人口流出地區(qū)生產(chǎn)性消費投入低、住房消費增長快。 三、人口流出地區(qū)糧食生產(chǎn)水平受糧食播種面積和農(nóng)業(yè)人口數(shù)量的影響。 四、人口流入地區(qū)經(jīng)濟發(fā)展水平較高、耕地保護壓力較大 最后,基于耕地和人口的視角,本文利用K-均值聚類法、波士頓矩陣模型劃分出四類不同的耕地利用保護區(qū),并提出了各個區(qū)域耕地保護的差異化戰(zhàn)略。
[Abstract]:China has made it its basic state policy to "cherish very much, make rational use of land and effectively protect cultivated land." China's cultivated land protection system emphasizes the dynamic balance of the total amount of cultivated land in various regions while neglecting the differences of cultivated land resource endowment and economic development level in different regions. The uncertainty brought about by the changes in population migration and the gap between urban and rural areas on the protection of the external environment of cultivated land has been neglected. In the past 20 years or so, the number of floating people in China has increased dramatically. Most of them are the rural population flowing from undeveloped areas to developed areas. The nature of the floating population and the characteristics of amphibious land occupation have a certain impact on the level of cultivated land utilization in each region. The study of the impact of floating population on the utilization and protection of cultivated land in the inflow and outflow areas can provide the basis for the formulation of dynamic and flexible cultivated land protection policies. The research of this paper includes three parts. Firstly, the regional distribution and characteristics of floating population and cultivated land resources are grasped through the calculation of the concentration degree of floating population, the concentration degree of cultivated land resources and location entropy, and the internal relationship between them is analyzed. Secondly, on the basis of census and agricultural census data, this paper makes use of simple correlation analysis, curve fitting and C-D function based on panel data. The effects of rural migrant labor force on the scale of cultivated land management, the input level of cultivated land, the change of cultivated land use mode and the cultivated land grain production capacity are revealed. This paper also explores the impact of rural migrant labor force on urbanization, construction land expansion and the indirect impact on cultivated land protection in the region. This part of the study draws four conclusions:. First, there is no positive interaction between labor force transfer and cultivated land scale management. Second, the population outflow area productive consumption investment is low, the housing consumption growth is fast. Third, the level of grain production in the outflow areas is affected by the planting area of grain and the number of agricultural population. Fourth, the level of economic development is relatively high in the areas where the population flows into the country, and the pressure on cultivated land protection is great. Finally, based on the perspective of cultivated land and population, this paper uses K-means clustering method, Boston matrix model to divide four different types of cultivated land use reserves, and put forward the different strategies of cultivated land protection in different regions.
