Structure, diversity and dynamics of natural-anthropogenic landscapes of Phu Yen province

The natural-anthropogenic landscape is a form of a modern landscape, formed on the common foundation of the geocomplex in which human activities become a basic factor participating in the creation and development of the landscape. Analysing the diversity and structure of the natural-antropogenic landscape is the basis for the planning of economic development, especially the agro-forestry economy as well as the conservation of biodiversity. Phu Yen Province is a coastal province of central Vietnam, but the western area is mostly hilly, bringing a high division of natural conditions, along with the typical economic development activities associated with indigenous culture. It is a territory with a high differentiation of natural and anthropogenic conditions, which is the foundation for the formation of a system of natural-anthropogenic landscapes with high diversity, including 1 system, 1 subsystem, 3 classes, 5 subclasses, 9 types and 132 kinds of landscape. Based on the results of the field survey and analyzed structure of the outstanding landscape types for Phu Yen Province, including natural forests, plantation forests, annual agricultural crops and perennial industrial plants. Biodiversity is expressed in the natural forest landscape type group distributed in the Hinh River - Deo Ca area, with the division of species according to different high belt structures. The annual agricultural crops are distributed largely across the river valleys and Tuy An plain, Tuy Hoa city. The group of plantation forests landscape is distributed on the form of low mountainous terrain, Son Hoa basalt plateau, Hinh River. The perennial industrial plants are distributed largely in western Phu Yen Province, with popular crops being Litsea glutinosa, Hevea brasiliensis, and Piper nigrum. Analysing the characteristics and structures of landscape types allows us to assess the suitability of the landscape for natural and socioeconomic conditions, which is the foundation for the orientation of agro-forestry economic development and biodiversity conservation for Phu Yen Province.
