- Abstract:

Biodiversity is the material basis of human survival, and it is of great significance to the development of human beings. Based on the theory of landscape security pattern, with the aid of graphics software, such as ArcGIS 10,Conefor Sensinode 2.2 and InVEST 2.2.0, the sources were identified, and minimum cumulative resistance surfaces were constructed by using minimum cumulative resistance model. The study area was divided into 3 resistance areas: the buffer for biodiversity conservation (the resistance value ranged from 0 to 8 242.16), the transition area for biodiversity conservation (the resistance value ranged form 8 242.16 to 20 509.57), and the restricted area for biodiversity conservation (the resistance value ranged from 20 509.57 to 49 069.63). Finally, the landscape security pattern of Beidaihe New District was constructed with the aim of biodiversity conservation. The results show that the proportion of core area for biodiversity conservation in the study area is 13.34%, and the land use types in this area include water and forestland; the proportion of buffer for biodiversity conservation in the study area is 30.64%, and the main land use types in this area are cultivated land, construction land, water and forestland; the proportion of transition area for biodiversity conservation in the study area is 34.41%, and the main land use types in this area are cultivated land and construction land; the proportion of restricted area for biodiversity conservation in the study area is 21.61%, and the main land use types in this area are cultivated land and construction land. According to the characteristics of the land use structure in each functional area, we put forward some suggestions for biodiversity conservation.
