【摘要】：河南省是我國農(nóng)業(yè)和糧食生產(chǎn)大省，在全國糧食生產(chǎn)方面占有舉足輕重的地位。隨著中原經(jīng)濟區(qū)建設上升為國家戰(zhàn)略規(guī)劃，既要保證“吃飯”又要保證“建設”的兩難局面在河南省表現(xiàn)尤為突出。因此結(jié)合當前的經(jīng)濟社會發(fā)展環(huán)境，開展城市化發(fā)展與耕地保護相關(guān)研究，對于實現(xiàn)城市化與耕地保護科學合理發(fā)展意義重大。 本論文在對2000－2008年耕地壓力指數(shù)相關(guān)要素進行分析的基礎(chǔ)上，測算了河南省和18個地市的耕地壓力指數(shù)，并從時間序列和空間尺度對耕地壓力進行深入分析；定性選取引起耕地壓力指數(shù)變化的驅(qū)動因素，利用主成分分析方法提取了主要驅(qū)動因素；對城市化率與耕地面積、耕地壓力指數(shù)進行相關(guān)分析，分別從時間序列上和空間尺度上分析城市化發(fā)展與耕地壓力指數(shù)的關(guān)系；在此基礎(chǔ)上提出河南省城市化進程中保護耕地的建議。得到如下結(jié)論： （1）河南省耕地壓力指數(shù)總體呈下降趨勢但空間分布不平衡。在糧食自給率為130%的水平上，河南省耕地壓力指數(shù)由2000年的1.0232增大到2003年的1.2754，后逐年減少至2008年0.9173。根據(jù)各地市耕地壓力指數(shù)值分布特征，全省共劃分為三個區(qū)域：1）耕地壓力明顯區(qū)，主要位于河南中西部，包括鄭州市、三門峽市、濟源市和平頂山市，其耕地壓力指數(shù)值都高于1，分別為1.4392、1.3336、1.0656、1.0240；2）耕地壓力預警區(qū)，主要位于河南中部和西南部，有洛陽市、開封市和南陽市，，其耕地壓力指數(shù)值在0.7以上；3）耕地壓力不明顯區(qū)，主要位于河南東部，有焦作市、周口市、新鄉(xiāng)市、濮陽市、信陽市、商丘市、鶴壁市和駐馬店市，其耕地壓力指數(shù)值在0.7以下，耕地無明顯壓力。 （2）影響河南省耕地壓力指數(shù)變化的主要驅(qū)動因素歸納起來可以分為經(jīng)濟發(fā)展、城市化發(fā)展、人口增長和農(nóng)業(yè)科技進步四個主要因素。 （3）耕地保護與城市化發(fā)展呈現(xiàn)一種對立統(tǒng)一的關(guān)系。2000－2008年間，河南省耕地面積和城市化水平呈顯著負相關(guān)關(guān)系，城市化水平每提高1個百分點，耕地面積減少1.23萬公頃。耕地壓力指數(shù)與城市化水平無顯著相關(guān)，且18個地市城市化發(fā)展與耕地壓力指數(shù)變化規(guī)律存在很大差異，具體可分為三類：1）以鄭州市、三門峽市、濟源市和洛陽市為代表的城市化率與耕地壓力指數(shù)同向變化；2）以平頂山市、鶴壁市和周口市為代表的城市化率與耕地壓力指數(shù)反向變化；3）以鶴壁市和濟源市為代表的城市化發(fā)展水平相同的地市之間耕地壓力指數(shù)相差很大。

[Abstract]:Henan Province is a major province of agriculture and grain production in China, which plays an important role in national grain production. With the construction of the Central Plains Economic Zone rising to the national strategic planning, the dilemma of ensuring both "eating" and "construction" is particularly prominent in Henan Province. Therefore, combined with the current economic and social development environment, it is of great significance to carry out the research on urbanization development and cultivated land protection in order to realize the scientific and reasonable development of urbanization and cultivated land protection. Based on the analysis of the related factors of cultivated land pressure index from 2000 to 2008, this paper calculates the cultivated land pressure index of Henan Province and 18 prefectures and cities, and analyzes the cultivated land pressure from time series and spatial scale, qualitatively selects the driving factors that cause the change of cultivated land pressure index, and uses the principal component analysis method to extract the main driving factors. This paper analyzes the correlation between urbanization rate and cultivated land area and cultivated land pressure index, analyzes the relationship between urbanization development and cultivated land pressure index from time series and spatial scale, and puts forward some suggestions for protecting cultivated land in the process of urbanization in Henan Province. The conclusions are as follows: (1) the cultivated land pressure index of Henan Province generally shows a downward trend, but the spatial distribution is not balanced. At the level of 130% grain self-sufficient rate, the cultivated land pressure index in Henan Province increased from 1.0232 in 2000 to 1.2754 in 2003, and then decreased to 0.9173 in 2008. According to the distribution characteristics of cultivated land pressure index, the province is divided into three areas: 1) the cultivated land pressure area is mainly located in the central and western Henan, including Zhengzhou City, Sanmenxia City, Jiyuan City and Pingdingshan City, the cultivated land pressure index value is higher than 1, 1.3336, 1.0656, 1.0240; 2) cultivated land pressure warning area, mainly located in central and southwest Henan, Luoyang City, Kaifeng City and Nanyang City, its cultivated land pressure index is above 0.7; 3) cultivated land pressure is not obvious, mainly located in eastern Henan, Jiaozuo City, Zhoukou City, Xinxiang City, Puyang City, Xinyang City, Shangqiu City, Hebi City and Zhumadian City, where the cultivated land pressure index is below 0.7, and there is no obvious pressure on cultivated land. (2) the main driving factors affecting the change of cultivated land pressure index in Henan Province can be divided into four main factors: economic development, urbanization development, population growth and agricultural science and technology progress. (3) there is a unity of opposites between cultivated land protection and urbanization development. During 2000 / 2008, there was a significant negative correlation between cultivated land area and urbanization level in Henan Province. for every 1 percentage point increase in urbanization level, cultivated land area decreased by 12300 hectares. There is no significant correlation between cultivated land pressure index and urbanization level, and there are great differences between urbanization development and cultivated land pressure index in 18 cities, which can be divided into three categories: 1) urbanization rate and cultivated land pressure index, represented by Zhengzhou, Sanmenxia, Jiyuan and Luoyang, 2) reverse change of urbanization rate and cultivated land pressure index represented by Pingdingshan City, Hebi City and Zhoukou City; 3) there is a great difference in cultivated land pressure index between Hebi city and Jiyuan city with the same urbanization development level.
