- Abstract:
-
Based on the map regarding the status quo of land use in its two different periods, combining with GIS and Fragstats software, this paper analyzed landscape patterns and ecosystem service values (ESV) of Luan County in 1996 and 2009. The results showed that its farmland landscape dominance index reduced, but its landscape dominance of construction land raised, landscape fragmentation index increased (aggravated), and landscape shape tended to be simple during the 13 years between 1996 and 2009. The total ecological service value decreased by 1.336×107 Yuan from 1996 to 2009, with construction landscape expansion the biggest single component. Moreover, the change of ecological service value and the evolution of agricultural landscape pattern were closely related, the variations of indices in patch area, patch type, patch number and fragmentation would cause the fluctuations of regional ecological service value. Therefore, it would be important to take measures including protection of the critical landscape types such as shrub, grassland, and woodland, increase of the patch size and connectivity, and reducution of the frequency and severity of disturbances to avoid further fragmentation, so as to ensure the ESV growth and the sustainable development of the study area.
