Cost-effectiveness Model of Water Ecosystem Self-purification
ثبت نشده
چکیده
The ecological forecasting of microorganisms and water quality dynamics in Krasnoyarsk reservoir is based on knowledge of dependence of specific growth rate (SGR) on limiting substrata. It investigated the influence of soil extract on the growth autochtonic bacterioplankton of Krasnoyarsk reservoir. The maximum SGR and Michaelis-Menten constant (on chemical oxidation decomposition (COD) permanganate) is determined. This parameters are used in ecomodel of Krasnoyarsk reservoir and Yenisei river to estimate the payoff of self-purification.

The Influence of Groundwater Depletion from Irrigated Agriculture on the Tradeoffs between Ecosystem Services and Economic Returns
An irrigated agricultural landscape experiencing groundwater overdraft generates economic returns and a suite of ecosystem services (in particular, groundwater supply, greenhouse gases reduction, and surface water quality). Alternative land cover choices indicate tradeoffs among the value of ecosystem services created and the economic returns. These tradeoffs are explored using efficiency front...
متن کاملDesigning payments for ecosystem services: Lessons from previous experience with incentive-based mechanisms.
Payments for ecosystem services (PES) policies compensate individuals or communities for undertaking actions that increase the provision of ecosystem services such as water purification, flood mitigation, or carbon sequestration. PES schemes rely on incentives to induce behavioral change and can thus be considered part of the broader class of incentive- or market-based mechanisms for environmen...
متن کاملThe Impact of Cropland Balance Policy on Ecosystem Service of Water Purification—A Case Study of Wuhan, China
Urbanization has been responsible for the loss of cropland worldwide, especially in China. Since this trend is expected to continue in the near future, China has implemented the strictest cropland protection policies in the world, to guarantee its national food security. However, the negative impact of cropland protection policies on ecosystem services has always been ignored. In this paper, we...
متن کاملRemoval of Heavy Metals from Waste Water Using Water Hyacinth
-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...
متن کاملEcosystem Services Valuation of Lakeside Wetland Park beside Chaohu Lake in China
Wetland ecosystems are one of the three great ecosystems on Earth. With a deepening of research on wetland ecosystems, researchers have paid more and more attention to wetland ecosystem services such as flood mitigation, climate control, pollution prevention, soil-erosion prevention, biodiversity maintenance, and bio-productivity protection. This study focuses on a lakeside wetland ecosystem in...
