- Abstract:
-
Source area is the foundation of constructing ecological landscape security pattern. Taking into account the effect of time dynamics, we propose a new methodology to improve source area recognition in order to lay foundations for the reasonable construction of ecological landscape security pattern. With the aid of software such as Fragstats 3.4,ArcGIS 10.0,Conefor Sensinode 2.2 and InVEST 2.2.0, we present a dynamic evaluation of landscape patch quality in three specific periods, respectively 1991, 2001 and 2013 in Beidaihe New District. All the final results of evaluation are divided into five levels, representing with numbers 1 to 5(the smaller the level, the better the quality of the patch). Afterwards, the classification results of the three years are superimposed, and the patches in level 1 and 2 are selected as the source area for landscape ecological security pattern in 2013. It turns out that the total source area in Beidaihe New District is 73.34 km2, accounting for 14.25% of the total area of Beidaihe New District. Among them, the patch of level 1 is 37.44 km2, which makes up 7.27% of the total area of Beidaihe New District; the patch of level 2 is 35.90 km2, presenting 6.97% of the total area of Beidaihe New District. The patches of source area mainly distribute in Aquatic Bureau and Seven Caspian Sea and surroundings, southeast of Liutaizhuang town and south of State-owned Forest. It is extremely essential to focus on the management and protection of these areas.
