“…However, a few studies have been done on landscape functions and features. These valuable constructions should be considered in any integrated planning and landscape design [23]. Purifying and treating processes, avoiding floods, and retaining and managing rainwater should not be concealed but, wherever possible, be presented openly and creatively.…”

The development of societies and the increasing growth of recent constructions, especially in cities, have caused environmental issues, destruction, and reduction of natural resources and the environment, especially green and green-blue spaces. According to studies, in the past years, many parts of natural and even pristine surfaces and spaces in big cities have been turned into artificial, and impermeable spaces, which has aggravated environmental and ecological problems and also it has aggravated the aesthetic characteristics of the urban landscape, particularly in arid and semiarid areas. In this case, the studies show that identifying and applying natural ecosystems such as wetlands and their artificial types due to their multifunctional aspects and benefits, especially in urban areas, can be the basis for reducing many issues mentioned. Therefore, it is necessary to pay attention to this critical issue and do more research to know different types of constructed wetland ecosystems along with their services and values. The primary aim of this research is to identify the values and services of this ecosystem and to examine the diverse patterns of constructed wetlands in order to extract and design simple patterns of construcred wetlands. We want to know their role and position in landscape architecture and urban planning and design process. Also, this study aims to examine the potencial and possibillity of building constructed wetlands in urban areas particularly in arid areas and Mediterranean regions, according to Koppen climate classiffication. In this regard, the theoretical framework is provided based on the study of specialized texts and the study of similar foreign case studies and diverse patterns of urban wetlands with their different functions. These reviews have been done in a specific format consisting of some main aspects, such as the function and supply sources of wetlands. The final result and extractted simplified patterns, according to case studies, can be considered as a framework for designing and planning urban constructed wetlands and a guide for planning and designing a landscape consisting of this element, especially in areas with arid, semiarid, and Mediterranean climates with hot and dry summers.

“…Most newly constructed wetlands are used for water treatment and habitat restoration for wildlife (Fennessy et al 1994;Vymazal 2007;Zhao et al 2015). To understand the functioning of newly constructed wetlands in terms of nutrient cycling, it is important to quantify production and decomposition rates.…”

Decomposition of Standing Litter Biomass in Newly Constructed Wetlands Associated with Direct Effects of Sediment and Water Characteristics and the Composition and Activity of the Decomposer Community Using Phragmites australis as a Single Standard Substrate

In a large-scale field experiment in 18 basins in a three-year old constructed wetland (6 ha) in the Netherlands, we analyzed a wide range of environmental variables, grouped into variable groups, to determine the combined direct effect of the environmental variables and the resulting decomposer community on decomposition rates of standing litter biomass in newly constructed wetlands. The variability among the experimental units could only to a limited degree be explained by linear combinations of all 54 possible predictor variables (30 and 23% of variation explained after 6 and 12 months of decomposition). Moreover, models for decomposition after 6 months could not predict decomposition after 12 months. The poor predictions by our models are probably due to (sometimes large) variations in the predictor variables but small differences in decomposition rates between the different basins. Based on our results it seems that decomposition of standing litter biomass in newly constructed wetlands is relatively uniform when considered in time and space, with low explanatory power by variable groups from biotic and abiotic variables. Normally one would expect differences in decomposition rates with differing environments, but counterintuitively in newly constructed wetlands these differences are small.

Drivers of Vegetation Development, Biomass Production and the Initiation of Peat Formation in a Newly Constructed Wetland

et al. 2019

Newly constructed wetlands are created to provide a range of ecosystem services, including carbon sequestration. Our understanding of the initial factors leading to successful peat formation in such environments is, however, limited. In a new 100ha wetland that was created north of Amsterdam (the Netherlands), we conducted an experiment to determine the best combination of abiotic and biotic starting conditions for initial peat-forming processes. Sediment conditions were the main driver of vegetation development, biomass production and elemental composition during the 3-year study period. Overall, helophytes (Typha spp.) dominated
