01-03-2016· Mineral resources carrying capacity evaluation index mainly involves economy, society, especially employment, and potential indicators. Marnika et al. (2015) formulated 36 indicators such as energy consumption, employment created, operational cost from the above three aspects for mining sites sustainable development. Chen et al. (2015) created the criteria of SDI and related pillar of ...
01-12-2018· After the 21 st century, studies of ecological carrying capacity, urban carrying capacity, and tourism traffic carrying capacity have gradually emerged. More scholars have begun to study the theory and methods of comprehensive carrying capacity investigations and apply them to various fields such as land, minerals, energy, and environmental protection.
The carrying capacity of resources was gradually noticed first due to the land resources shortage. The accelerated process of industrialization made the research of single factor resource carrying capacity gradually extended to the water resources, mineral resources and forest resources because it started to have problem in these areas.

The evaluation of resource and environmental carrying capacity (RECC) is the foundation for the rationale behind the arrangement of land spaces for production, living, and ecological uses. In this study, based on various natural, economic, and social factors, an integrated Multi-Factor assessment model was developed to evaluate the RECC of Xinbei district of Changzhou.
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained in that specific environment, given the food, habitat, water, and other resources available. In population ecology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium, which may be far below an ...
Flotation Column Cells can only ‘carry’ or recovery so much froth/concentrate for any given diameter. Unlike a mechanical cell on which you can just turn-on more air to recover more metal, column cells with not respond that way. A column cell can only carry so much froth to the concentrate launder. Their concentrate production is ‘Maxed-Out’ by design. Flotation Column Cell have a ...
With the rapid development and expansion of the cities in China, the carrying capacity of resource and environment has become a huge concern for local governments. From the perspective of geological environment, geological disasters are the main restraining factor of the development in mountain cities. This study was conducted in Suide County of Shaanxi Province with a risk-based approach as ...

Carrying Capacity: a “measurement” (actual or estimated) of how much forage a unit or piece of ground is able to produce on an average year. The carrying capacity is the maximum stocking rate possible that is consistent with maintaining or improving forage and other vegetation and related resources.
Carrying capacity measures what level of use is sustainable. However, its initial application was to only one product – the number of cattle which could be fed. In fact, carrying capacity is much more complex, particularly when a very wide range of valued products and …

In der Ökologie ist die Tragfähigkeit die maximale Zahl von Organismen einer Art (Populationsgröße), die in einem Lebensraum für unbegrenzte Zeit existieren können, ohne diesen nachhaltig zu schädigen. Häufig wird die Tragfähigkeit mit der (Umwelt-)Kapazität in Populationsmodellen, die auf der logistischen Gleichung aufbauen, gleichgesetzt.
From four dimensions of economy, society, potential and environment, we select seven indicators including economy scale, contribution to GDP and employment, guarantee period, the discharge of industrial waste water, sulfur dioxide and smoke dust to build the evaluation index system of Mineral Resources Carrying Capacity (MRCC).
Applying the economic carrying capacity of mineral resources as an evaluation index system,the model which was combined with static and dynamic evaluation techniques was built and the constraint mechanism was also analysed for the ecological environmental capacity.The empirical analysis based on scenario analysis for the coal resources of Fujian Province shows that the static economic carrying ...
13-08-2020· Carrying capacity, the average population density or population size of a species below which its numbers tend to increase and above which its numbers tend to decrease because of shortages of resources. The carrying capacity is different for each species in a habitat because of that species’
This paper establishes the indicator system and evaluation models in population carrying capacity of mineral resources and calculate the dimensions of population carrying capacity and determines the carrying capacity of mineral resources for the year 2000 and the year 2010 in China.
01-04-2015· 1. Introduction. The concept of carrying capacity is rooted in demography, biology, and applied ecology (Clarke, 2002).In ecology, carrying capacity is defined as the maximum population of a species that a habitat can support without permanent impairment of the habitat's productivity ().Water resources carrying capacity (WRCC) is a new concept that has not yet been clearly defined and …

Carrying Capacity Differentials and Adjustments The tests of usefulness for a carrying capacity-based planning process are found in the capability of such a process to 1) articulate differen- tials (short-falls, excesses, trade offs) between "desired" (normative) 119
