Soil and vegetation are the most sensitive elements for the variation of karst environment. The weathering of carbonate is important soil formation mechanism in karst area, but its soil forming ability is so poor that the thickness of soil layer becomes thin by the water erosion, though the soil loss is insignificant but serious. The karst process, the ecology process, the hydrology process are three important circulation mechanisms in the karst multiple media environment. In the Chinese North and South karst area, the eco-environmental protection and restoration has already been the important part as the national territorial resources and the environmen- tal comprehensive development and management. The character of karst plants mainly depends on the environmental conditions, i.e. lack of water, richness of Ca, poor soil and shortage of organic matter. The plants have low growth pace and low life-form resource; it is vulnerable under the disturbance of irrational human activities. Therefore, the rocky desertification is the final result of karst ecosystem degradation. But ecological condition is severe in the North and South karst area, especially in the south karst stone mountainous area and the north arid karst area. There are many problems with the eco-environmental protection and restoration. This paper takes the karst multiple media environment as a core, comprehensively discusses the relations of the three processes – karst, hydrology, and ecology, and puts forward the direction of the research on karst ecology hydrology and the future.展开更多

Differ from ecologists and environmentalists who regard industrial ecosystem as the natural ecosystems in which material, energy and information circulates, this paper defines industrial ecosystem as a set of factors that are vital to the development of a certain industry and their interrelationship. The industrial ecosystem consists of three sub-systems that are innovation ecosystem, production ecosystem, and application ecosystem, and subsidiary factors that include factor supply, infrastructure, socio-cultural environment, international environment and policy system. The industrial ecosystem is characterized by interdependencies, complex interactions, self-recovery and co-evolution. The development of an industry is' the result of the reaction of the whole industrial ecosystem; therefore, the competition in strategic emerging industries among countries is in essence the competition in industrial ecosystems. Those countries which are able to take the lead in setting up complete industrial ecosystem will occupy advantage in developing strategic emerging industries. Cultivating and developing strategic emerging industries requires promoting the development and coordination of the whole ecosystem.展开更多

Most of the countries along the Silk Road in the 21st century are developing countries, and the majority of them are facing the same ecological and developmental difficulties as China. In this paper, under the background of the “OBOR” strategy and on the basis of the distribution of global climate types, we selected Central Asia and Northwest China, which have temperate continental climates, as the research objects. We sorted out and summarized the main ecological problems faced by Western China and Central Asia during the development of the “Belt and Road” initiative. At the same time, in combination with the major ecological governance projects implemented in recent years, we proposed key ecological governance technologies that have a certain degree of scalability, such as key technologies for water resource utilization and protection, sand prevention and control, and saline-alkali land governance. The aim was to offer the experiences and a reference for providing technological models for the “one belt along the road” region and the country to build an effective ecological governance system. Two suggestions are then proposed for improving the feasibility and rationality of ecological governance technology in the construction of the “One Belt, One Road”. 1) With the implementation of the strategy of “OBOR” construction, the ecological threats the OBOR countries are facing cannot be ignored. Every country needs to jointly act to build an “OBOR” ecological civilization. 2) The participants must pay attention to the spatial heterogeneity and temporal dynamics of ecological carrying capacity, and provide data reference and support for the reasonable allocation of ecological governance technology.展开更多

Speciation however may also proceed via other scenarios, such as when populations experience directly se- lected or random divergence in mate recognition systems. The relative contributions of magic trait versus other scenarios for speciation remain virtually unexplored. The present study aims to test the relative contribution of the magic trait scenario in the divergence of populations of the medium ground finch Geospiza fortis of Santa Cruz Island, Galapagos. First, we assess differ- ences in G. fortis song between a northern population (Borrero Bay) and a southeastern population (El Garrapatero), differences that we propose (along with other within-island geographic song variations) have arisen via scenarios that do not involve a magic trait scenario. Pairwise comparisons of raw and composite (PC) song parameters, as well as discriminant functions analyses, re- veal significant patterns of song divergence between sites. Second, we test the ability of territorial males at Borrero Bay to dis- criminate songs from the two sites. We find that G. fortis males can discriminate within-island song variants, responding more strongly to local than to "foreign" songs, along 3 raw and 1 composite response measures. Third, we compare these findings to prior data sets on song divergence and discrimination in Santa Cruz G. fortis. These comparisons suggest that song divergence and discrimination are shaped less strongly by geographic sources than by morphological (beak-related) sources. We thus argue that interpopulation song divergence and discrimination, fundamental elements of assortative mating in Darwin's finches, can be fos- tered in early stages of divergence under magic trait as well as alternative scenarios for speciation, but with more emphasis on the magic trait scenario, at least for this species on this island [Current Zoology 59 (1): 8-19, 2013].展开更多

文摘The goal of ecological civilization construction is to realize the harmonious coexistence of human and nature.Land is the spatial carrier of ecological civilization construction.Land use types or behaviors reflect the level of intensive use of land resources,leading to different ecological environmental effects,thereby affecting the level of regional ecological civilization construction.This issue,"Land Use and Ecological Civilization",discusses the theory and method of land use management in the view of ecological civilization from the aspects of land use efficiency,land use change,land multi-functional trade-off,land ecosystem service and land ecological risk by selecting 14 representative papers,providing practical reference for the formation of the land use mode and behavioral system of ecological civilization.With abundant research levels,this issue covers varied research scales such as village,county and province,various landform types such as plain and hill,and typical land use areas at home and abroad such as East China,Central China,Northwest China,Yangtze River Economic Belt and Japan.Being frontier and practical,the multidisciplinary research methods in this issue include literature research method,fractal theory,qualitative comparative analysis,VAR model,and econometrics,among others.Focusing on the prominent problems in the process of land use,this issue deeply discusses the hot topics such as land ecological efficiency,spatial behavior characteristics,land use structure optimization and ecological risk assessment.This issue not only reviews the current literature on urgent land use issues such as arable land abandonment and land use risk,but also tries to conduct trade-off and synergy analysis on the varied functions of the rural landscape and ecosystem,thus providing a theoretical and empirical basis for solving land use problems from the perspective of ecological civilization.This issue reflects the realistic urgency of guiding land use with the concept of ecological civilization,and provides theoretical guidance and technical support from the aspects of methods and research framework.Finally,this issue proposes five hot topics in the field of land use research from the perspective of ecological civilization in the future,namely,ecological management of land use structure,ecological evolution mechanism of land use process,land ecological use mode,early warning and regulation of land ecological security pattern,ecological management and control of land use behavior.
