【摘要】：當(dāng)前我國(guó)正處于城鎮(zhèn)化快速發(fā)展的階段，耕地利用情況也在發(fā)生著巨大的變化。在耕地面積減少的背景下提升耕地集約利用水平是實(shí)現(xiàn)城鎮(zhèn)化與耕地保護(hù)和糧食安全協(xié)調(diào)的重要途徑，對(duì)我國(guó)新型城鎮(zhèn)化的實(shí)現(xiàn)具有重要的意義。城鎮(zhèn)化和耕地集約利用相互聯(lián)系和相互制約，城鎮(zhèn)化與耕地集約利用的協(xié)調(diào)發(fā)展程度決定著城鎮(zhèn)化建設(shè)水平和我國(guó)耕地產(chǎn)出水平的高低。本文以我國(guó)287個(gè)設(shè)區(qū)市為例，通過(guò)分別構(gòu)建城鎮(zhèn)化發(fā)展與耕地集約利用評(píng)價(jià)指標(biāo)體系，進(jìn)行數(shù)理統(tǒng)計(jì)分析與耦合協(xié)調(diào)模型計(jì)算分析，梳理揭示兩者之間的關(guān)系，進(jìn)而提出了結(jié)論和促進(jìn)城鎮(zhèn)化建設(shè)與耕地集約利用的相關(guān)對(duì)策與建議。 （1）大規(guī)模的人口集聚可以帶來(lái)城鎮(zhèn)化的全面發(fā)展，城市經(jīng)濟(jì)的發(fā)展對(duì)城鎮(zhèn)化水平的提高有很大推動(dòng)作用。土地城鎮(zhèn)化的提高對(duì)總城鎮(zhèn)化的提升沒有明顯效果。社會(huì)城鎮(zhèn)化成熟的城市總城鎮(zhèn)化也比較成熟，但是總城鎮(zhèn)化水平高的城市并不一定社會(huì)城鎮(zhèn)化高。 （2）我國(guó)設(shè)區(qū)市耕地集約利用水平差異較為明顯，最集約利用的城市與最粗放利用的城市耕地集約利用水平相差近16倍之多。我國(guó)華北、華中、華東和華南區(qū)域耕地集約利用水平普遍較好，而高水平耕地集約利用的城市主要集中于東南沿海組團(tuán)、四川東部地區(qū)和中部糧食主產(chǎn)區(qū)三大組團(tuán)區(qū)域。耕地集約利用必須要以較高的耕地投入強(qiáng)度為支撐。 （3）經(jīng)過(guò)相關(guān)分析與偏相關(guān)分析，可確定耕地投入強(qiáng)度和耕地總集約度與人口城鎮(zhèn)化、經(jīng)濟(jì)城鎮(zhèn)化、土地城鎮(zhèn)化和城鎮(zhèn)化總水平之間存在顯著的正相關(guān)關(guān)系，但是沒有線性關(guān)系。即人口城鎮(zhèn)化、經(jīng)濟(jì)城鎮(zhèn)化、土地城鎮(zhèn)化和城鎮(zhèn)化總水平的提升，，可以帶來(lái)耕地投入強(qiáng)度和耕地總集約度的提升。耕地投入強(qiáng)度和耕地總集約度與社會(huì)城鎮(zhèn)化之間沒有明顯的相關(guān)關(guān)系。 （4）從地域分布上看，我國(guó)城鎮(zhèn)化水平高、經(jīng)濟(jì)基礎(chǔ)較好、開發(fā)程度較高的華北地區(qū)、長(zhǎng)三角地區(qū)、珠三角地區(qū)城鎮(zhèn)化與耕地集約利用耦合協(xié)調(diào)關(guān)系較好，而東北地區(qū)、西北地區(qū)、華中地區(qū)和西南地區(qū)耦合協(xié)調(diào)性較差。深圳市、廣州市、北京市、上海市等26座城市，城鎮(zhèn)化與耕地集約利用發(fā)展水平均相對(duì)較高，基本形成了彼此互為依托、相互促進(jìn)的格局，這些地區(qū)城鎮(zhèn)化的發(fā)展強(qiáng)力地促進(jìn)了耕地的集約利用。經(jīng)濟(jì)城鎮(zhèn)化和土地城鎮(zhèn)化對(duì)耕地集約利用的提升具有顯著的促進(jìn)作用。
[Abstract]:At present, China is in the stage of rapid development of urbanization, and the utilization of cultivated land is also undergoing tremendous changes. Raising the level of intensive utilization of cultivated land under the background of decreasing cultivated land area is an important way to realize the coordination of urbanization with cultivated land protection and food security, which is of great significance to the realization of new urbanization in China. Urbanization and intensive utilization of cultivated land are interrelated and restrict each other. The coordinated development of urbanization and intensive utilization of cultivated land determines the level of urbanization construction and the level of cultivated land output in China. In this paper, 287 districts and cities in China are taken as an example. By constructing the evaluation index system of urbanization development and cultivated land intensive utilization, mathematical statistics analysis and coupled coordination model calculation and analysis are carried out to reveal the relationship between the two. The conclusions and suggestions of urbanization construction and intensive utilization of cultivated land are put forward. (1) Large-scale population agglomeration can bring about the overall development of urbanization. The development of urban economy has a great role in promoting the level of urbanization. The improvement of land urbanization has no obvious effect on the overall urbanization. The total urbanization of the cities with mature social urbanization is also mature, but the cities with high level of total urbanization are not necessarily high in social urbanization. (2) the level of intensive utilization of cultivated land in cities with districts in China is quite different. The level of intensive utilization of cultivated land in the most intensive cities is 16 times higher than that in the most extensive ones. The intensive utilization level of cultivated land in North, Central, East and South China regions of China is generally good, while the cities with high level cultivated land intensive utilization are mainly concentrated in the southeast coastal areas, the three major groups of regions in the east of Sichuan and the main grain producing areas in the central part of Sichuan. The intensive utilization of cultivated land must be supported by high input intensity of cultivated land. (3) through correlation analysis and partial correlation analysis, it can be determined that the intensity of cultivated land input, the total intensity of cultivated land, the urbanization of population, the urbanization of economy, and so on. There is a significant positive correlation between urbanization and the total level of urbanization, but there is no linear relationship. That is, population urbanization, economic urbanization, land urbanization and the total level of urbanization can lead to the increase of input intensity and total intensity of cultivated land. There is no obvious correlation between cultivated land input intensity and total cultivated land intensity and social urbanization. (4) in terms of regional distribution, China has a high level of urbanization, a good economic base, and a high degree of development in North China. The coupling and coordination between urbanization and cultivated land intensive utilization in Yangtze River Delta and Pearl River Delta are better than that in Northeast, Northwest, Central China and Southwest China. In Shenzhen, Guangzhou, Beijing, Shanghai and other 26 cities, the level of urbanization and intensive use of cultivated land is relatively high, which basically forms a pattern of mutual support and promotion. The development of urbanization in these areas has strongly promoted the intensive use of cultivated land. Economic urbanization and land urbanization play a significant role in promoting the intensive use of cultivated land.
