As hydropower project construction and ecological support systems become more interdependent, new disciplines are needed to assess this ecological effect. An ecological footprint model of the hydropower project is presented based on the emergy theory (Em-EF). Modifications have been made to the Em-EF model, in response to its perceived shortcomings. The emergy of additional capacity of reservoir should be included in the renewable natural resources account. Further, the same emergy density should be used to calculate the ecological capacity supplied account and the ecological footprint occupied account. The aim of this paper is to show a modified ecological footprint calculation for the hydropower project. A large-scale (Ⅱ) hydropower project is selected as an example for the application. To demonstrate the mechanics of this modified method, we compared our calculations with the conventional one. The same conclusion is drawn using both methods: the ecological deficit of the hydropower project will occur before the design equilibrium year. But, the needed time to offset the ecological deficit is different. The modified model gives an even rational result than the conventional one.

The ecological footprint demand and ecological capacity for the six types of productive land during 2005~2010 are calculated using the ecological footprint model in this paper by taking Dongying City as the example, and the ecological deficit of Dongying City is thereby figured out. Based on this, the indicators such as the ecological footprint of 10k yuan GDP, the ecological pressure index, the ecological diversity index, and the social economic development index, etc representing the sustainable development are calculated and analyzed, to learn that it is not allowed to be optimistic about the ecological environment in Dongying in recent years, as the ecological deficit has increased year after year, and the ecological pressure has become heavier and heavier. However, it is learned through analysis of the ecological footprint of 10k yuan GDP and the social economic development index that under the situation when the ecological pressure on economic growth in the ecological economic system of Dongying is increased, a tendency exists for the consumptive and extensive economic growth pattern to gradually step towards the ecologically intensive pattern, but it is still required to make more efforts in the aspects of reducing the ecological footprint demand and improving the ecological capacity.

Reasonable use of land or not, directly related to the sustainable development of a country or region. This paper introduced the basic concept, calculation formula and method of the ecological footprint. We calculated the ecological footprint of Shenzhen by application of the ecological footprint model. The results showed that the per capita ecological footprint in Shenzhen in 2011 was approximately 2.486 hm2, while the per capita ecological capacity was approximately 0.0597 hm2, the per capita ecological deficit was approximately -2.433 hm2, and the ecological footprint is about 47.33 times greater than the ecological capacity. Finally, we discussed the limitations of applying the ecological footprint model to judge the sustainable use of land in this paper.

The paper calculates ecological footprint per capita and ecological capacity per capita in the Jilin province during 1998 and 2010 by using the ecological footprint theory, and analyzes the dynamic changes of ecological footprint per capita and ecological capacity per capita, and obtains development prediction model of ecological footprint per capita and ecological capacity per capita based on grey prediction model. The results indicate the ecological footprint per capita had increased continuously from 1.7841 hm2 per capita to 3.2013 hm2 per capita between 1998 and 2010. During this period, ecological capacity per capita dropped from 1.3535 hm2 per capita to 1.3028 hm2 per capita. Ecological deficit had increased from 0.4306 hm2 per capita to 1.8985 hm2 per capita that showed that the development of Jilin province was in an unsustainable status. The gray prediction model shows the ecological footprint per capita in the Jilin province will increase from 3.4833 hm2 per capita to 5.7022 hm2 per capita between 2011 and 2020, ecological capacity per capita will drop from 1.2978 hm2 per capita to 1.2676 hm2 per capita and ecological deficit will increase from 2.1855 hm2 per capita to 4.4346 hm2 per capita.

In the field of hydropower project, the overabundance of information from multiplex data sources has forced managers and decision makers to spend much time dealing with information they need. Therefore the research on project simulation system is quite necessary. If system can provide some construction plan and schedule of the project properly, it will greatly improve the effectiveness of the plan. After the analysis of specific projects’ process and demands, this paper puts forward a visual simulation solution to large-scale hydropower construction, which including visual simulation model, design of algorithms and system implementation. Based on SOA structure, the optimization model and the simulation results’ 3D visualization are provided and a virtual three-dimensional world of the complicated coordinal construction process is proposed, with the advantage of direct viewing and real-time interactive, facilitating effective technical support for the decision of project construction design, and greatly enhancing the information level of design and organization of large-scale hydropower projects.

As one of the most developed and competitive metropolitan areas in the world, the contradiction between resource depletion and sustainable development in the Guangdong-Hong Kong-Macao Greater Bay Area (GHMGBA) has become a crucial issue nowadays. This paper analyzed the natural capital utilization patterns in GHMGBA during 2009–2016 based on a three-dimensional ecological footprint model. Ecological carrying capacity intensity (ECintensity) was calculated to optimize the accounting of ecological carrying capacity (EC). Ecological footprint depth (EFdepth) and ECintensity were quantitatively investigated and influencing factors were further explored based on a partial least squares (PLS) model. Results showed that GHMGBA had been operating in a deficit state due to the shortage of natural capital flow and accumulated stock depletion. The highest EFdepth occurred in Macao (17.11~26.21) and Zhongshan registering the lowest (2.42~3.58). Cropland, fossil energy and construction land constituted the most to total ecological deficit, while woodland was continuously in a slight surplus. Natural capital utilization patterns of 11 cities were divided into four categories through hierarchical clustering analysis. Driving factors of EFdepth, ECintensity and three-dimensional ecological deficit (ED3D) were mainly students in primary and secondary education, disposable income, consumption expenditure, R&D personnel and freight volume. Our findings could provide guidance for decision-makers to develop resource utilization portfolios in GHMGBA.
