Abstract:

The research of the arable land use transitions and its impact on the ecological environment from the dual perspective of arable land occupation and supplement can provide scientific basis for sustainable land use and ecological protection. This paper chose coastal areas in Jiangsu Province as a case where the economy develops rapidly and there are serious problems of land use. Based on the land use data in Jiangsu coastal areas (1990, 2000, and 2010), the models of arable land use transitions and ecosystem service value were synthesized with GIS. The methodology of ecosystem service value calculation from R. Costanza et al. was used to analyze arable land use transitions in two phases, 1990-2000 and 2000-2010, and the Geo-spectrum of arable land use transitions model and ecosystem service value during 1990-2010 was acquired. Then, the article studied spatio-temporal variation characteristics of arable land use transitions and its response of ecosystem service value change in Jiangsu coastal areas. The results showed that: 1) During 1990-2000, the occupation of arable land was mainly caused by construction land, water body and grassland, and the supplementary of arable land was from construction land, water body, forestland, and grassland. The occupation of arable land was more than the supplementary of arable land during 1990-2000. The most obvious changes were “arable land → construction land” and “grassland → arable land”, with low spatial separation degrees. 2) During 2000-2010, unused land became another type of occupation of arable land, and grassland was still the main supplementary of arable land. The most obvious changes was “arable land → construction land” and “arable land → water body”, and the spatial separation degree became larger. The occupation of arable land was still more than the supplementary of arable during 2000-2010. 3) The most obvious arable land use transitions mostly happened in the later period of 1990-2010. 4) The total value of ecosystem service increased from 17.085 billion yuan to 18.223 billion yuan during the past two decades in Jiangsu coastal areas, in which water body is the most important contribution to the ecosystem service value. Arable land use transitions resulted in the decrease of ecosystem service value of arable land, in which “arable land → construction land” was the main impairment of ecosystem service value.
