基于GIS的区域经济空间结构演化研究--以河南省为例

文章基于GIS,以河南省为例,对区域经济空间结构演化进行研究,通过对IDW方法和Kriging方法的比较,认为利用IDW方法对一个区域经济的空间结构进行研究更为合适。并且在区域经济研究中,利用GIS技术实现了经济数据与图形数据之间的关联,使区域经济的空间结构模式和发展趋势以图形的形式清晰直观地表现出来,增强了其可视性,更利于问题的发现、分析和解决,从而为促进区域经济空间结构的优化提供了科学依据。

提高火电行业排放标准对中国经济和污染物排放的影响——基于环境CGE模型的测算

通过利用环境CGE模型测算实施《火电厂大气污染物排放标准GB 13223-2011》对中国宏观经济和污染物减排的短期影响。模拟结果显示,短期内,新标准对宏观经济的影响较小,GDP只下降了0.18%。从行业产出看,要素价格下降,使工业部门和出口导向型行业成本降低,产出扩张。此外,新标准对大气污染物减排的效果显著。由于脱硫脱硝装置的投入使用使末端废气去除率提高,进而导致煤炭燃烧排放量大幅下降,SO₂和NO_X的排放量分别下降22.8%和11.4%,绝对量分别减少560万t和148万t。     

Effectiveness of farmland transfer in alleviating farmland abandonment in mountain regions

Farmland abandonment is a type of land use change in the mountain region, and this change is under rapid development. Whether farmland transfer can prevent this process and promote the effective allocation of land resources or not is a question worth studying and discussion. With the help of the previous research findings, the objective of this paper was to find out the role of farmland transfer on preventing farmland abandonment, by using the methods of multiple view with two factors, and single factor correlation analysis. The results showed that: (1) At village level, a significant negative correlation between farmland transfer and farmland abandonment existed in the study site, with R² = 0.7584. This correlation of farmland with high grade farming conditions presented more outstandingly. The fitted curve for the farmland at Level I had the largest R² at 0.288, while that for the farmland at Level IV had the smallest R² at 0.103. Which indicated that farmland transfer could prevent the abandonment of farmland with high grade farming conditions? (2) At plot level, the abandonment rate of farmland with high grade farming conditions was significantly lower than that of farmland with poor grade farming conditions. It was the lowest at 10.49% for the farmland with Level I farming conditions, whereas the farmland with Level I farming conditions was 26.21%. Abandoned farmland was mainly contributed by farmland with Level IV farming conditions in the study site. (3) At village level, the role of farming conditions on farmland abandonment was insignificant. The univariate correlation analysis revealed that the abandonment ratio was negatively correlated with the proportions of farmland at Levels I and II and their accumulated proportion; however, their R² were small at 0.194, 0.258, and 0.275, respectively. The abandonment of farmland with high farming conditions still existed. The abandonment ratios of farmland at Levels I and II were high at 9.96% and 10.60%, respectively. This presented that farmland transfer on behalf of the land rental market was still not developed. (4) However, the village possessed the high rate of farmland transfer, and its rate of farmland abandonment with high grade farming conditions was all lower. When the transfer ratios of farmland were over 20%, the abandonment ratios of farmland at Levels I and II were 6.47% and 6.92%, respectively. Farmland abandonment was still controlled by the improvement of land rental market. And the functions of land rental market optimizing the utilization of farmland resources have been presented to a certain degree. (5) To further improve the marketing degree of land rental, the probability of farmland abandonment could be reduced. Especially, their function to farmland with high grade farming conditions was very obvious, and could avoid the waste of farmland resources with high grade farming conditions.

Contrastive Study of the Circular Economy of Coal Resource City Based on Ecological Efficiency and C Model

Being a developing country, the evaluation of Chinese circular economy should have its particular criterion that suits for specific national conditions. With the growth of economy, Chinese environmental loads should be permitted to increase at an appropriate speed. Based on this concept, this paper divides the process of evaluation into two parts which include evaluation of development level and evaluation of development performance. Firstly, this paper sets up a reference system which includes Zaozhuang City of Shandong Province, Jiaozuo City of Henan province, Shizuishan City of Ningxia Hui Autonomous Region and China that is regarded as a region respectively, analyzes the development level of circular economy of coal resource cities based on the evaluation indicator of ecological efficiency, and puts forward the future direction of circular economy of coal resource cities. Secondly, based on C Model of Circular Economy, this paper constructs the measurement model of development performance in which study regions are analyzed in a particular period that is from 2000 to 2020, and evaluates the development performance of circular economy for study regions according to the relationship of growth multiples between economic scale and environmental loads. We can draw several main conclusions: firstly, the development pathways of all four study regions belong to type Ⅱ which resource efficiency is preferred. Secondly, the comprehensive energy consumption efficiencies of coal resource cities were left far behind by China’s average level. Thirdly, the circular economies of all study regions have achieved remarkable progress. Fourthly, the development level of circular economy can be evaluated from two dimensions which consist of horizontal comparison method and vertical comparison method. Fifthly, C model is an appropriate development model that suits for Chinese national conditions and could be selected as an important method to evaluate regional development performance of circular economy.
