英文摘要 | Human activity intensity is a synthesis index for describing the effects and influences of human activities on land surface. this paper presents the concept of human activity intensity of land surface and construction land equivalent, builds an algorithm model for human activity intensity, and establishes a method for converting different land use/cover types into construction land equivalent as well. an application in china based on the land use data from 1984 to 2008 is also included. the results show that china's human activity intensity rose slowly before 2000, while rapidly after 2000. it experienced an increase from 7.63% in 1984 to 8.54% in 2008. it could be generally divided into five levels: very high, high, medium, low, and very low, according to the human activity intensity at county level in 2008, which is rated by above 27%, 16%-27%, 10%-16%, 6%-10%, and below 6%. china's human activity intensity was spatially split into eastern and western parts by the line of helan mountains-longmen mountains-jinghong. the eastern part was characterized by the levels of very high, high, and medium, and the levels of low and very low were zonally distributed in the mountainous and hilly areas. in contrast, the western part was featured by the low and very low levels, and the levels of medium and high were scattered in gansu hexi corridor, the east of qinghai, and the northern and southern slopes of tianshan mountains in xinjiang. |
