- Abstract:

In order to analyze the dynamic changes of ecological-living-industrial land, a transitional geographical space, and explore their driving factors, a classification system of ecological-living-industrial land was constructed based on the data of karst landform and Beibu Gulf Economic Zone,the transition matrix and the dynamics of land use were adopted to analyze the dynamic changes of ecological-living-industrial land in recent 38 years, and the driving forces of such changes were explored by geographic detector. The conclusions are as follows.(1)Horizontally, the changes of ecological-living-production land in research area during past 38 years were that, ecological land decreased, living land expanded outward from urban areas, and production land kept unchanged; the total area with functional change was about 25 538.63 km2, accounting for 26.73%;(2)from the vertical perspective, the production and living lands decreased as the rise of slope and altitude, in other words, ecological land occupied most areas with higher slope and altitude; vast tracts of ecological land at lower slope and altitude had given way to living and production lands, while the opposite was the case at higher slope and altitude;(3)the geographical detector had identified that, the production and ecological lands were under great impact of natural resource conditions and social economy, such as DEM, population density, etc.; and the living land was deeply affected by social economy and geographic location, including production output value, population density, road density, etc. With population growth and economic development, land for living and industrial production in the southwest Guizhou-Beibu Gulf region has occupied agricultural and ecological land with low slopes and low altitudes. It is important to strengthen the control of the expansion of land for construction to ensure food security and ecological safety.
