Integration of InVEST-Habitat quality with landscape pattern indexes: A case study of Mondulkiri province in Cambodia
Many attempts have been carried out to halt the biodiversity loss and deforestation, both from the management and policy side. The development of RS, GIS, satellite tracking and ecological model, quantification and visualization of the regional biodiversity evaluation at spatial scale and time scale was widely used. Landscape biodiversity was the premise foundation for identifying key biodiversity protection areas at geographical scale. Empirical studies had been conducted for biodiversity evaluation and spatial pattern based on InVEST model. Cambodia is of global conservation importance which still contain nearly intact species assemblages. The purpose of this study is to look at the spatial and temporal changes in land use and to derive patches with high habitat quality by tracking changes in habitat quality according to the characteristics of landscape metrics and changes in Mondulkiri province in Cambodia. (1) Observation of land use change patterns (2) Examine major landscape change factors, and examine the extent to which landscape patches contribute to securing habitat quality. Hoping the results could be used to support spatial planning and protection of biodiversity, especially for the fragile mountainous area. Mondulkiri has undergone a relatively strong process of land-use change. the most notable characteristic was a transformation from forest land into cropland or plantation during the 30 years. Landscape proportion reduced from 0.59 to 0.52, indicating that as the proportion of forest area patches decreased. Number of patches increased from 394 to 725 which means landscape patches become more fragmented and similarly patch density slightly increased. The northern and eastern parts of the Mondulkiri are dense crop areas with a high proportion while the southern regions have a large number of plantation land. The results could be used to support spatial planning and protection of biodiversity, especially for the fragile mountainous area.
