Abstract:
|
The Vietnamese Wetlands Classification System is an important basis for governmental
agencies, non‐governmental organizations, and scientists to identify wetlands that are underrepresented
in the List of Wetlands of International and National Importance in order to encourage
their designation and appropriate long term management. The classification also serves as a broad
framework to aid the rapid identification of the main wetland habitats represented at each site, to
provide units for mapping, and to encourage uniformity of concepts and terms in national wetland
inventory.
The Vietnamese Wetlands Classification System is a hierarchy of systems, subsystems, classes,
and types or sub‐types of wetlands. The systems are defined based on salinity of water or distance
of wetland from the sea ‐ marine/coastal wetland (salty/brackish wetlands) and inland wetland
(freshwater wetlands). The subsystems are based on the main origin of wetlands – natural or
artificial wetlands. The classes are defined based on the hydrological regime, they would be
permanent or non‐permanent (covered by water) wetlands. The most important level in the
classification system is the types. The types are defined based not only on geomorphologic,
geologic features and origin of wetlands, but also the dominant life form of vegetation or
physiography and composition of substrate features. Further, the modifiers of the classification
systems (sub‐types) can be added based on relevant criteria and using objectives; they must be
developed by the users.
There are 38 wetland types defined in the classification system purpose to ensure uniformity
throughout the whole country and to serve individuals or organizations with varied interests and
objectives. Building the Vietnamese Wetland Classification System is necessary now, when
sustainable use of natural resources is an important task of development course of Vietnam. |
