Ecological-hydrological processes in arid environment: Past,present and future

Ecohydrology, aiming to study the interactions between terrestrial ecological systems and hydrological cycles as well as their impacts on water management, has been an emerging interdisciplinary research field since the 20th century. It hosts both natural and human regulated processes that are potentially coupled in complex ways. Understanding the ecological-hydrological processes, the fundamental mechanisms and the connections between them is critical since these processes are not isolated but integrated to impact basin- scale hydrological and biogeochemical functioning of a larger river system, especially in arid environment where water resources are considered to be the source of life. Thus, research on ecological-hydrological processes in arid environment is not only a scientific focus area but also important to sustainable development. Research projects and initiatives involved in observation, measurement, modeling and data assimilation have been well-developed for those purposes over the past 20 years. This review summarizes the historical development of ecohydrology science in China and the state-of-the-art tools available in the research framework. Five grand scientific challenges are listed as prospects and exciting opportunities for the scientific community. To advance the current ecological-hydrological processes research, scientists from multidisciplinary backgrounds (such as geography, geology, geomorphology, hydrology, geochemistry and ecology), need to unite to tackle the many open problems in new dimensions.

环境伦理观与可持续旅游行为研究进展

环境伦理观是促进人与环境和谐发展的核心理念,对可持续旅游行为具有积极的指导作用。本文通过对中英文主流数据库期刊的文献回顾,对环境伦理观的理论内涵、影响因素以及环境伦理观对可持续旅游行为的影响进行系统梳理。结果表明：环境伦理观的概念体系主要包括环境道德、环境情感和环境信念三要素。现有研究往往不区分环境道德和环境信念,对环境情感的度量往往缺乏统一标准,导致研究结果不一致。对环境伦理观具有直接影响力的是价值观理论,社会文化因素、宗教因素、教育水平、媒体和广告影响、政策、国内和国际移民经历等因素也有一定的作用。西方对环境伦理观与可持续旅游行为进行了大量的定性和定量研究,而国内以概念性研究居多,既有研究中往往仅关注旅游中的环境行为,对可持续旅游行为关注较少,缺乏对这一特定行为的概念界定,因此,未来应在以下几个方面加强研究：①对环境伦理观理论内涵的度量;②对环境伦理观影响因素的研究;③对可持续旅游行为的界定和度量;④文化因素对于环境伦理观和可持续旅游行为的影响;⑤运用定量和定性研究方法探求环境伦理观对可持续旅游行为的作用机理和影响,为促进生态文明建设提供理论支撑和实证研究。

城市生态足迹计算与分析——以广州为例

生态足迹是近年来较为流行的定量测度人类对自然利用程度的新方法。生态足迹分析可定量反映城市人类活动对自然生态环境产生的压力和影响程度,为城市生态系统研究提供了新的思路和研究方向。本文以广州市为案例,估算2000年广州市的生态足迹,并分析了1995～2000年间广州生态足迹动态变化过程。结果表明:2000年广州市生态足迹为2.5ha/人,当地生态承载力为0.2ha/人,生态足迹是生态承载力的12倍半;近5年间万元GDP生态足迹逐年下降,但人均生态足迹略有上升。这说明广州市总体上经济发展方式正逐步由粗放型转变为集约型,但今后仍需注重提高其资源利用效率,提倡节约型的生产和生活消费模式,减少其生态足迹,逐步迈向生态城市,实现城市的可持续发展。

A review of soil and water conservation in China

The preservation and sustainable development of soil and water resources is one of the basic principles for the development of China. Throughout the course of history, all the social improvement and economic development are deeply concerned with soil loss and ecological environmental protection. It is now a common sense that soil and water conservation is the safety insurance for national ecology and its development. For the past long period of time, soil and water loss has been recognized as "the No.1 killer" to the ecological environment. The nation is on the stage of the critical conditions for its development. China has massive mountain and upland area with complicated geological conditions and accelerated human destruction and serious soil and water loss. Based on rich historical documents, renovating experience and detailed analysis of the data collected in field experiments and field surveys for soil and water conservation, this paper aims to review the general characteristics of soil and water loss, to explore the relationship between soil and water conservation and sustainable economic development, and to provide relevant strategies for soil and water conservation in China.

The Progress of Resources and Environment Carrying Capacity: from Single-factor Carrying Capacity Research to Comprehensive Research

As a concept to describe development restrictions, resources and environment carrying capacity (RECC) research has developed over more than 100 years since it was first proposed at the beginning of the 20^th century. It is now regarded as a significant factor in evaluating the level of cooperation between regional population, resources, and environment; and it is currently used as an effective and operational tool to guide regional sustainable development. This article first reviews the origin of RECC and its early headway. It then reviews the historical development of RECC from single factors, such as land resources carrying capacity, water resources carrying capacity and environmental carrying capacity (environmental capacity), to more comprehensive research, such as comprehensive evaluation, emergy analysis, and ecological footprint analysis. In general, it appears that comprehensive research will become increasingly important in RECC research. However, there are several deficiencies in the current state of comprehensive research. Firstly, comprehensive RECC research lacks a common measurement standard, though some scholars have attempted to create one. Secondly, the RECC evaluation of open systems and dynamic studies should be strengthened. Thirdly, more attention should be paid to standardization, digitalization, and systematization to promote the applicability of RECC research to national practical demands.

The Current Status,Problems and Prospects of Researches on the Carrying Capacities of Ecological Environment in China

Determining the carrying capacity of ecological resources is the key to finding contradictions between human activities and the environment, as well as the links between economic growth, environmental protection and social development. In recent years, the carrying capacity of the ecological environment has been extensively studied at home and abroad. Through extensive literature research and analysis, this paper discusses the current status and main problems of recent research on the carrying capacity of the ecological environment in China. For example, two of the main problems are that: 1) the concepts and connotations are not clear enough, and 2) the research content is not systematic enough. This is followed by a summary of the evaluation index system and main calculation methods. Finally, according to the research status and development trends at home and abroad, the possible direction for the development of this research field in the future is proposed.
