“…The interactions between natural processes and ecosystem structure of wetlands lead to that these ecosystems are capable of performing their functions which significantly bring to various benefits to humans, often known as wetlands ecosystem services [6]. The enormous values of wetlands ecosystem have been acknowledged in many ecosystem services assessment studies [7][8][9][10][11].…”

“…The enormous values of wetlands ecosystem have been acknowledged in many ecosystem services assessment studies [7][8][9][10][11]. Nevertheless, there are two important things of wetland functions which should be clearly perceived, including (1) wetlands do not entirely carry out the same functions; and (2) between different wetland types, an extent or intensity of one function is also not implemented as the same level [6]. Therefore, in recent years much attention has also been paid to identification and recognition of potential functional features rather than plain descriptions of characteristic wetlands [6].…”

“…The results are needed to manage and preserve the wetlands systematically. Among these methods, the hydrogeomorphic approach has been adopted to eliminate drawbacks of other methods in the context of strengthening management and conservation capacity of wetland sites by reasonable classification and assessment of wetlands [6,12].…”

“…Based on regimes of (a) hydrology; (b) geomorphology; and (c) soil, the HGM approach divides the landscape of wetlands into hydrogeomorphic units; therefore, in this study, the HGM approach is also used as the hydrogeomorphic unit delineation approach, hereafter referred to as the HGMU delineation approach [6]. A hydrogeomorphic unit is a landscape unit having uniform conditions of hydrology, geomorphology, and soil; in which, under normal conditions, soils should also be required homogeneous because the hydrology and geomorphology of wetlands are reflected through the soil types [19].…”

Wetlands account for about 41% of the total global ecosystem services value; therefore, they preserve a role as the most precious ecosystems on Earth. However, 35% of global wetland areas have been lost since 1970 as many wetlands have been exploited unsustainably. In this context, a hydrogeomorphic delineation approach has been developed to divide a wetland landscape into units which have homogeneous hydrological regime, geomorphology, and soil, named as hydrogeomorphic units (HGMUs). These units are fundamental units of a wetland for functional and resilience assessment of a wetland in different uses; then, to determine optimal management strategies for maintaining its complete ecosystem functions. This study used Tram Chim National Park for applying the hydrogeomorphic delineation approach for breaking a landscape of the park down into HGMUs. The findings showed that the park may be divided as three classes, including depression, riverine, and flat. Each class continued to be subdivided as subclasses. The results showed that there were six subclasses, i.e. six HGMUs, which identified in the park. Based on the results, the study described characteristics of HGMUs and created maps of HGMUs distribution of the park. These results will be a basis for next steps of applying functional assessment procedures for analyzing potential of the HGMUs to perform ecosystem functions in our upcoming study for preservation and management purposes in Tram Chim National Park.
