To avoid this, it is essential to seek shade to avoid the influence of short-wave length solar radiation. In addition, natural ground surfaces such as green spaces and water surfaces are useful in reducing the air temperature. It is indispensable to consider climate mitigation effect of outdoor space. The purpose of this study is to clarify the influence of the thermal environment of an outdoor space on the human body in rural and suburban regions where paddy fields remain. Subject experiments were conducted to examine the relationship between the thermal environment evaluation index enhanced conduction-corrected modified effective temperature (ETFe) in an outdoor space and the physiological and psychological responses of the human body. Experiment sites were selected with consideration for the natural ground surface such as bare ground where the surface is gravel or soil;paved ground such as concrete, asphalt or blocks;green areas covered in plants;and water surfaces, as well as the sky factor due to buildings or trees etc. and the proportion of the solid angle of components of greenery and water etc. comprising the solid angle of the total celestial sphere. A ground surface feature with a high heat capacity may promote sensation of hot and deteriorate the thermal sensation. A landscape of thick vegetation with a high green factor may have a strong feeling of confinement, which can make it somewhat hot and somewhat uncomfortable thermal environment due to the sense of stagnation. Compared with the urban environment, it is conceivable that the difference in the perceptual environment, whereby it is subconsciously assumed to be a comfortable thermal environment, had an effect in the rural and suburban regional environment, resulting in an ETFe lower than the upper limit of comfort in a summer urban environment.展开更多

Chinese agricultural and rural policies characterized by state intervention and government leadership have played an important role in promoting agricultural development and increasing farmers’ incomes as well as balancing development in urban and rural areas. However, the effectiveness of current agricultural policies in promoting agricultural productivity is now clearly leveling off. Given this situation, the authors argue that it is imperative to construct a new analytical framework featuring government regulation and guidance of agricultural and rural development. In this framework, the government must clearly define the boundaries between its activities and those of the market and rural social organizations. While fully respecting the fundamental role of the market in allocation of resources and rural self-management, the government should exercise its power as a backstop. Further, the government needs to establish a logical sequence for government functions such as formulating the basic operating system of the market and society, correcting market failure and social dysfunction and cultivating market/social entities. To use this new analytical framework to strengthen and improve its regulation and guidance of agricultural and rural development, the government needs to reform the basic rural management and agricultural support and protection systems and to pay attention to the cultivation of market entities in agricultural production on the basis of agricultural marketization. Furthermore, it needs to construct a basic urban-rural integrated public service system with the government as the leading actor, carry out innovations in the management system of rural society and fully mobilize the social forces to take part in the administration of public affairs. It also needs to reconstruct the system of government administration and management to ensure the thorough implementation of agricultural and rural development policies.展开更多
