略论朱熹“敬论”

朱熹“敬论”既继承了程颐主敬说，而又有全面的理论整合及发挥，是其整个理学思想的重要一环。朱熹由其“心是做功夫处”的心论立场出发，极力反对在心的操舍存亡的功夫论问题上预设“另有心之本体”的前提，与此相应，其主敬功夫也就不是道德本心的直接发动，而是对心的知觉意识等各种功能的控制调整，其云“敬只是此心自做主宰处”、“以敬为主而心自存”、“将个敬字收敛个身心”、都是在这个意义上说的。然朱熹主敬自有一套理路，其核心关怀在于如何解决现实人心的障蔽问题，未尝不是儒学功夫论的一种理论形态。     

General Nexus Between Water and Electricity Use and Its Implication for Urban Agricultural Sustainability:A Case Study of Shenzhen, South China

Although water and energy resources are well-recognized concerns regarding economic and social development sustainability, little specific research has focused on both water and energy problems at the same time. This study analyzed the water and electricity-use patterns in Shenzhen, South China during 2001-2009. A curve regression method was used to examine the relationship between water and electricity use per gross domestic product (GDP) in Shenzhen and its three sectors, i.e., agriculture, industry & construction, and residential life & services. Results showed that agriculture only covered less than 10% of water and electricity use in Shenzhen, while industry & construction and residential life & services accounted for more than 90% of water and electricity use in Shenzhen, which coincided with the city’s industrial structure. The water and electricity use per GDP in agriculture was the biggest among three sectors in Shenzhen during 2001-2009, which means inefficiency of water and electricity use in agriculture. Due to transitioning to advanced materials and manufacturing, both water and electricity use per GDP in industry & construction decreased during 2001-2009 and their utilization efficiencies gradually increased over time. The same held true for those in residential life & services transformed toward modern business, creative culture, finance services, etc. Derived from the survival of the fittest in competing for limited water and electricity resources, agriculture in Shenzhen has been gradually substituted by industry & construction and residential life & services, with much higher efficiencies of water and electricity use. And traditional agriculture will not be sustainable in the process of urbanization and industrialization, except high-tech intensive agriculture with low water and energy cost. Furthermore, by means of curve regression, we found that there was a significant quadratic relationship between water use per GDP and electricity use per GDP in the entire city and its three sectors. Suitable industrial transformation and advancement was a very effective way to save water and energy for modern cities. This can provide some reference for systematic planning and design of water and electricity allocation and use in agriculture, industry & construction and residential life & services in a city.     

在社会经济与森林资源因子约束下的我国林业区划研究——基于Kohonen网络聚类

在林业区划理论的指导下，根据林业统计年鉴公布的2009年的相关数据，本文选取社会经济因子与森林资源因子两方面的相关指标进行基于Kohone网络的聚类分析，以探究我国各地区林业产出与森林资源现状及两者之间的相关性。在社会经济与森林资源因子约束下，将全国区划为资源最充沛——林业较发达地区，资源较充沛——林业最发达地区，资源最匮乏——林业发展一般地区和资源较匮乏——林业欠发达地区四个区域。经过分析发现，产值最高的区域其资源不一定是最充沛的，相反，资源最匮乏的区域产值也不一定是最低的，两者之间没有绝对的正相关关系。     

How does industrial agglomeration affect regional innovation? A spatial econometric analysis

This study empirically investigates the direct and indirect (spillover) effects of three types of industrial agglomeration with different cognitive distances, namely, industrial specialization, industrial related variety, and industrial unrelated variety, on regional innovation. Accordingly, we applied the concepts of related and unrelated variety and used spatial econometric analysis. Based on panel data of 283 Chinese cities from 2004 to 2016, the empirical results reveal that both industrial specialization and industrial related variety significantly improve regional innovation and produce positive spatial spillover effects on the surrounding regions. However, industrial unrelated variety has a significant negative impact on regional innovation and produces a negative spatial spillover effect on the surrounding regions. Moreover, the direct and indirect effects of the three types of industrial agglomeration on regional innovation between China's coastal and inland cities. The findings have important theoretical and policy implications.

Soil conservation on road embankments using palm‐mat geotextiles: field studies in Lithuania

The application of geotextile mats constructed from the palm leaves of Borassus aethiopum (Borassus) and Mauritia flexuosa (Buriti) was investigated in field experiments. The use of geotextiles caused improved soil moisture storage during dry summer periods on a steep (21–25°) roadside slope in Lithuania. The enhanced soil moisture under the Borassus and Buriti mats encouraged better root development of perennial grasses, increased the number and weight of earthworms and increased the dry biomass of perennial grasses by 50.5 and 18.2%, respectively, compared with a grassland control. The mean rate of water erosion from bare soil during the study period from 17/04/2007 to 11/12/2008 was 33.21 Mg/ha. The cover of palm‐mat geotextiles decreased soil losses from bare fallow soil by 94.8–91.1%. An erosion rate of 0.85 Mg/ha over this 21‐month period was measured on the slope under perennial grasses without geotextile cover. Application of geotextile cover on perennial grasses completely prevented soil erosion by water. Therefore, use of geotextiles has clear soil and water conservation benefits on industrial slopes susceptible to erosion. The use of geotextiles has multiple benefits including soil conservation, the improvement of plant growth conditions and the encouragement of earthworm populations.
