Source Data

In recent years, ecosystem service values (ESV) have attracted much attention. However, studies that use ecological sensitivity methods as a basis for predicting future urban expansion and thus analyzing spatial-temporal change of ESV are scarce in the region. In this study, we used the CA-Markov model to predict the 2030 urban expansion under ecological sensitivity in the Three Gorges reservoir area based on multi-source data, estimations of ESV from 2000 to 2018 and predictions of ESV losses from 2018 to 2030. Research results: (i) In the concept of green development, the ecological sensitive zone has been identified in Three Gorges reservoir area; it accounts for about 35.86% of the study area. (ii) It is predicted that the 2030 urban land will reach 211,412.51 ha by overlaying the ecological sensitive zone. (iii) The total ESV of Three Gorges Reservoir area showed an increasing trend from 2000 to 2018 with growth values of about USD 3644.26 million, but the ESVs of 16 districts were decreasing, with Dadukou and Jiangbei having the highest reductions. (iv) New urban land increases by 80,026.02 ha from 2018 to 2030. The overall ESV losses are about USD 268.75 million. Jiulongpo, Banan and Shapingba had the highest ESV losses.

Outdoor tourism is a form of outdoor holiday that is growing rapidly today, and that stands out from other forms of tourism for its immediate relationship with the landscape which becomes for the tourist the main attraction of the holiday intended as a break from ordinary urban life. Outdoor tourism today represents a growing percentage in the tourism sector, in which mobile homes are the real players. Despite the considerable use of this product in open-air accommodations located in relevant landscapes, there is still no sensitivity in the constructive approach and in the choice of materials in terms of sustainability. In the open-air tourism sector, the lack of ecological sensitivity results from two levels of application: one regarding the whole settlement and the public spaces of outdoor accommodations and one regarding the mobile unit from the design to the production process. This paper will provide some practical strategies to introduce the ecological theme in the mobile home for the tourism sector. The research aims to analyze the production system of mobile homes in order to introduce alternative materials within the existing assembly line. The research demonstrates the possibility of a product being sustainable both economically and environmentally, healthy, and well-integrated with landscape by adopting an approach that makes it possible to use the same assembly line currently in use.

<p>This article aims to present the productivity of the assumptions of Philosophical Hermeneutics (Gadamer, 1996) and his discovery of the logical, ontological and structural model of the game that takes place during the experience that is the basis of comprehension. Thus, digital games are proposed as manners, methods and ways to improve the understanding, interpretation and application of the concepts of Sustainability and Environmental Principles. The attraction of the game as a pedagogic space lays in the fact that it takes over and allows the player to internalize ecological sensitivity, something that happens during the play. Finally, the results show an augment on students’ motivation, when using the game versus the traditional process.</p>

An experiment on three dry bean varieties (Start, Hópehely, Diana), using different sowing-times, fertilizers and plant densities was performed on sandy soil in the University of Debrecen, Centre for Agricultural Sciences, Research Institute of Nyíregyháza in 2015. The aim of the experiment was to study which treatment gives the highest yield, and whether the different treatments result in significant differences in the yields. In this paper the dry bean yield at ‘Diana’ variety is analyzed. The treatments were done with three fertilizer doses and three plant densities at different sowing-times (April 24; May 8; May 18). As a result of the high temperature and the drought during the growth season, the yields we harvested were in low, which shows the ecological sensitivity of the plant we examined. We concluded that the poorest yield was harvested at the third sowing-time. There was no significant difference in the yields at the first and second sowing- time. Examining all the three fertilizer treatments we applied at the experiment, we achieved the highest yields in the control plots. It might be due to the weak efficiency of nitrogen fertilizer under the extremely dry conditions. The highest yield was harvested at the control treatments during the second sowing-time. Regarding the effect of the plant densities, the highest crop yield was achieved at the treatment using 400 000 germs ha-1, followed by 300 000 germs ha-1 and 200 000 germs ha-1.

AbstractThe construction of ecological security pattern is one of the important ways to alleviate the contradiction between economic development and ecological protection, as well as the important contents of ecological civilization construction. How to scientifically construct the ecological security pattern of small-scale counties, and achieve sustainable economic development based on ecological environment protection, it has become an important proposition in regulating the ecological process effectively. Taking Fengxian County of China as an example, this paper selected the importance of ecosystem service functions and ecological sensitivity to evaluate the ecological importance and identify ecological sources. Furthermore, we constructed the ecological resistance surface by various landscape assignments and nighttime lighting modifications. Through a minimum cumulative resistance model, we obtained ecological corridors and finally constructed the ecological security pattern comprehensively combining with ecological resistance surface construction. Accordingly, we further clarified the specific control measures for ecological security barriers and regional functional zoning. This case study shows that the ecological security pattern is composed of ecological sources and corridors, where the former plays an important security role, and the latter ensures the continuity of ecological functions. In terms of the spatial layout, the ecological security barriers built based on ecological security pattern and regional zoning functions are away from the urban core development area. As for the spatial distribution, ecological sources of Fengxian County are mainly located in the central and southwestern areas, which is highly coincident with the main rivers and underground drinking water source area. Moreover, key corridors and main corridors with length of approximately 115.71 km and 26.22 km, respectively, formed ecological corridors of Fengxian County. They are concentrated in the western and southwestern regions of the county which is far away from the built-up areas with strong human disturbance. The results will provide scientific evidence for important ecological land protection and ecological space control at a small scale in underdeveloped and plain counties. In addition, it will enrich the theoretical framework and methodological system of ecological security pattern construction. To some extent, it also makes a reference for improving the regional ecological environment carrying capacities and optimizing the ecological spatial structure in such kinds of underdeveloped small-scale counties.
