Life satisfaction approach to farmers' compensation for land acquisition:empirical study from the suburbs of Wuhan City

Farmers' compensation for land acquisition is not only critical to increasing their income and to playing a pivotal role in maintaining rural stability,but also to the promotion of sustainable land use.Based on analysis of Chinese land acquisition policy under the Land Management Law,which provides principles or guidelines for determining compensation according to agricultural land use in regard to farmers' previous quality of life,the Life Satisfaction Approach is introduced in this article to evaluate farmers' compensation for land acquisition.Employing data from a questionnaire survey on 346 farming households in Wuhan Suburbs,this article examined the influence of farmland on farmers' life satisfaction and evaluated the level of compensation for land acquisition.Results show that farmland has a significantly positive impact on life satisfaction,which fell by 0.033 on a five-point scale following a reduction farmland by of 1 mu.Respondents were willing to accept approximately RMB 3066.44 annual household income for the loss of 1 mu farmland;the level of compensation after discounting by 6.2%is RMB 750,000 per hectare.It was found in a further comparative study that the level of farmers' compensation for land acquisition is decidedly low,and it was also shown that their compensation standards,as well as the actual compensation,could be substantially improved by expanding economic compensation to non-economic compensation to embody farmland multifunction in terms of production and non-production against farmers' previous quality of life.This article proposes a compensation model that enriches the content of land acquisition compensation,extends the current literature on measuring compensation,and provides economic theory bases for increasing compensation standards and improving policies related to land acquisition.We consider that if this compensation model is applied,it could raise the cost of land acquisition and improve usage of land,reduce the speed of rural-urban land conversion,and improve farmers' well-being.

Study on the Current Situation and Countermeasures of Rural Domestic Sewage Treatment in Beijing City

In recent years,the construction of rural sewage treatment in Beijing City has developed rapidly,but there are still many problems in some rural domestic sewage treatment. In this paper,the current situation of rural domestic sewage in Beijing City is combed,and its characteristics are summarized. Meanwhile,the current situation of rural domestic sewage treatment in Zhejiang Province,Hunan Province and Shandong Province is summarized by consulting relevant data. By comparing with current situation of rural domestic sewage treatment in Beijing City,it is found that there are some problems in the treatment of rural domestic sewage in Beijing City,such as unsuitable treatment mode,unreasonable discharge requirements and inadequate treatment technology. Therefore,some countermeasures and suggestions are proposed,such as strengthening the investigation,research and planning,and differential formulation of the sewage treatment discharge standards,and establishing modular treatment technology system. It is hoped that this paper will be helpful to the treatment of rural domestic sewage in Beijing City.

The Seasonal Rainfall Forecast in Nanning City in 2019 with the Method of Trend Comparison Ratio (TCR)

In this paper, the monthly rainfall statistical data of Nanning City, Capital of Guangxi Zhuang Autonomous Region, China, from 2006 to 2018, were collected. On the basis of qualitative analysis of the rainfall seasonal changing law, the non-linear seasonal rainfall forecast model on Nanning City with the method of Trend Comparison Ratio (TCR) was established by the statistical analysis software Office Excel 2013. The model was used to predict the rainfall in spring, summer, autumn and winter in Nanning in 2019. The results were: 286.41 mm, 695.79 mm, 292.20 mm and 118.11 mm, respectively. It was also found that the predicted results were consistent with the seasonal distribution characteristics, annual distribution characteristics and the trend of historical rainfall time series fluctuation, through the qualitative analysis of figures. Compared with the actual measured rainfall data of Nanning City in 2019 in the China Statistical Yearbook (2020), the predicted values are basically consistent with the measured values.

人口密度与城市宜居性关系的一般性规律探索

建设宜居的生活环境是人类社会实践一直追求的目标,而优化城市人口密度是改善城市宜居环境的重要途径。本文在梳理相关学科理论基础上,以中国城市和美国城市作为主要研究案例,比较不同情境下人口密度与城市宜居性关系的研究结果,总结人口密度和城市宜居性的关系规律。研究发现,在低密度情境下,提高人口密度有助于缩短出行时耗,减少空气污染,提高居民身体健康水平和主观幸福感;而在高密度情境下,提高人口密度却会延长出行时耗,加剧空气污染,损害居民身体健康水平和主观幸福感。基于此,本文认为在兼顾低密度和高密度情境下,人口密度与城市宜居性之间的关系应遵循更具一般性的倒U型规律,即在低密度情境下,提高人口密度有助于增加城市宜居性;而在高密度情境下,提高人口密度则会降低城市宜居性。

“中心—外围”视角下东北地区市域经济韧性及影响因素分析

随着中国经济进入“新常态”,东北地区再陷发展困境,区域经济韧性面临严峻挑战。针对中国市辖县体制的地域型城市,通过比较“中心—外围”的经济韧性关系,更有助于认知东北地区的经济发展问题。本文以东北地区市域中心市区和外围县市作为研究对象,分析2007—2019年东北地区市域中心市区和外围县市的经济韧性水平、类型的时空演变特征,采用地理探测器探究中心市区和外围县市经济韧性的影响因素。结果发现:①东北地区中心市区和外围县市经济韧性水平均变差,且外围县市变化更大。市域经济韧性类型变多且变得更差。②东北地区中心市区和外围县市经济韧性的主要影响因素具有相似性,产业结构、政府管控对经济韧性具有重要影响,劳动力市场和金融环境的影响程度偏弱。③部分影响因素在中心市区和外围县市的作用方向不同,产业结构多样化水平和固定资产投资占GDP比重有助于提升中心市区经济韧性,但对外围县市经济韧性表现为负向作用。
