Evaluation on Emergency Ability of Agricultural Envrironmental Pollution Incident in Central Plains Economic Zone

Abstract The level of emergency ability directly reflects response effect of an area to emergency. Taking Central Plains Economic Zone as re- search object, by documents retrieval, field survey, mechanism analysis and logical reasoning, evaluation index system for emergency ability of ag- ricultural environmental pollution incident was established, which included 5 first grade indexes, 19 second grade indexes and 53 third grade inde- xes. By mechanism analysis and mathematical derivation, evaluation model for emergency ability of agricultural environmental pollution incident： I =m∑i=1∑j=1Pij, On this basis, four prefecture-level cities （A, B, C and D） of Central Plains Economic Zone were evaluated by using the index system and the evaluated model. The research could provide important theoretical reference for emergency ability construction of agricultural environmental pol- lution incident in Central Plains Economic Zone.

Development Plan for Under- forest Economy of Henan Province Based on Central Plains Economic Region

Firstly,this paper analyzed current situations,major practice and existing problems of under-forest economy in Henan Province.Then,it made an in-depth discussion of guiding thought,principle and objectives,construction task and safeguarding measures of the underforest economic development plan. Besides,it analyzed benefits of the under-forest economic development plan. By 2017,the area of underforest economic land will reach 1. 60 million hm2,create output value of 155. 2 billion yuan( accounting for more than 20% of forest output value),provide 3. 27 million jobs,and will greatly increase ecological carrying capacity of construction and development of the Central Plains Economic Region( CPER).

Spatial Heterogeneity Analysis of PM2.5 Concentration in Central Plains Economic Region

The research of the spatial heterogeneity of PM2.5 concentration in an area, is of great significance for understanding its regional spatial distribution structure, exploring the transmission relationship between regions, in order to formulate joint prevention and control measures within the entire area. Based on the daily monitoring data of PM2.5 concentration in the Central Plains Economic Region in 2019, this paper utilizes cluster analysis to divide the regional PM2.5 concentration into 5 classes, builds their spatial semi-variogram model, and then utilizes interpolation analysis method to study the regional overall distribution characteristics and transmission law. The results show that the PM2.5 concentration in the Central Plains Economic Region has a medium or higher spatial autocorrelation. The critical value of the overall PM2.5 concentration in the area is 150 μg/m3, as the overall PM2.5 concentration less than the value, the PM2.5 in a region mainly comes from local emissions, as the overall PM2.5 concentration higher than the value, the influence of spatial structure on the distribution of PM2.5 concentration is gradually obvious. PM2.5 has a certain degree of spatial transmission, which mainly includes two routes as Puyang-Xingtai and Puyang-Zhengzhou, and the transmission intensity of the former is greater than the latter.

Research on Urban Agricultural Scientific Development Path of the Construction of Central Economic Region

The significance of developing characteristic agriculture in Central Economic Zone was elaborated from four aspects of three modernizations coordinated development,guaranteeing city supply of agricultural products,creating more jobs for farmers,making agriculture more significant.

Investigation on the Regional Branding Mode of Modern Agriculture in Guanzhong-Tianshui Economic Zone——From the Perspective of Country-of-origin Image

The theory of the country-of-origin image is discussed and the natural relations between county-of-origin image and the regional brand are explored.The paper points out that the dispersion of agriculture has intensified the natural relations to a large extent.The paper probes into the branding status of agriculture in Guanzhong-Tianshui economic zone and points out the problems of it.In the first place,the agricultural industrial system is complete but there is no unified agricultural regional brand;in the second place,the weak awareness on protecting brand leads to the irrational behaviors on damaging brand.From the perspective of the image of the country of origin,the branding mode of agriculture is established and the countermeasures on improving the competitiveness of agricultural products are put forward.Firstly,the leading role of the government should be fully displayed;secondly,the image protection of original production place and regional brand promotion of the agricultural region should be intensified;thirdly,the functions of local pillar industries in protecting image and regional branding should be fully made use of.

基于时空演变对中原区经济发展差异的计量分析

为促进区域协调发展,首先,将人均GDP作为衡量经济发展水平的指标,并采用Dagum基尼系数等方法,测度分析2012—2019年中原经济区经济发展差距的时空演变趋势;其次,引入产值影响力分析郑州对中原经济区的产值影响度及综合影响度,并构建ARIMA预测模型对未来8年郑州对中原区经济影响力度进行预测.结果表明,一方面,近年来中原经济区各地区之间的绝对差距在逐年扩大,中原经济区区域间经济发展差距主要源于郑州都市圈与中原副中心城市群以及郑州都市圈与其他城市群之间,郑州都市圈和其他两个区域之间的经济发展差距对总差距的贡献率均在40%以上,中原经济区各区域间的经济发展差距大于各区域内的发展差距;另一方面,郑州对中原经济区整体影响力不断提高,且未来8年将继续推动地区经济发展.

中原经济区建设背景下河南文化旅游产业融合发展研究

中原地区作为华夏文明的摇篮,文化旅游资源极其丰富.长期以来,河南文化旅游资源的内涵挖掘缺乏深度,文化表达技术手段落后,文化旅游资源优势并未得到充分释放.中原经济区的文化战略定位和旅游发展目标,为河南文化旅游产业融合发展带来契机.中原经济区文化旅游产业融合发展,将在保护文化、传承文明和推动文化旅游产业转型升级方面起到重要推动作用.但中原经济区建设中,文化旅游产业融合发展存在着制度障碍、科技创新障碍和能力障碍等问题.为促进河南文化旅游产业融合发展,需要从放松产业管制、借力文化旅游产业园区和推进大型文旅集团建设等几个方面着手.

中原经济区土地经济密度区域差异及影响机理

评价区域土地经济密度并研究其内在影响机理对指导区域城市健康可持续发展具有重要指导意义。文章以中原经济区为研究对象,分析30个城市2002-2012年间的土地经济密度,并采用空间分析法和面板数据模型对土地经济密度的区域差异和影响机理进行探讨。结果表明:(1)中原经济区土地经济密度总体呈不断上升趋势,但个别城市近年来有所下降;(2)土地经济密度总体差异上下波动有缩小趋势,其中核心区区内差异是总体差异主要来源;(3)土地经济密度在整体上没有显著空间集聚,各城市土地经济密度呈现随机分布状态;(4)人口规模、经济水平、城市化水平和产业结构对土地经济密度具有显著影响,且呈正相关态势。

中原经济区县域经济差异时空演变研究

中原经济区干线公路路网通达性研究

利用GIS空间分析工具,选取最短时间矩阵、最短路径矩阵、路网密度及通达性系数等指标,对中原经济区干线公路路网通达性进行分析。结果表明:中原经济区公路总长度和高速公路长度逐年快速增加,国道和高速公路分别呈现出"四横五纵"和"米"字型布网。郑州、开封、许昌和新乡因优越的干线公路基础条件和中心地理位置,位居公路路网总距离和总时间排名的前列;运城市、蚌埠市和晋城市则因边缘效应而排名相对靠后。郑州和洛阳的交通中心地位明显,特别是郑州的中心地位更加突出,但以二者为中心交通运输最短时间分布状况欠佳,2 h圈内的城市数量较少。研究区总路网密度较高,区域内路网总容量较大,服务能力和辐射能力较强。高密度路网主要分布在中东部,低密度则分布在北部、西部和南部。高通达性城市主要分布在山东省和河南省,低通达性城市主要分布在河北省、山西省、安徽省及河南省部分省辖市,郑州市干线公路通达性最好,蚌埠市最差。自然地理位置、经济发展水平及交通建设资金投入是影响公路路网通达性的主要因素。
