摘要
基于临安昌北山区2010、2015和2020年土地利用监测数据,根据行为主体的主观用地意图为“三生”用地划分依据,依据土地利用转移矩阵、土地利用变化图谱、单一土地利用动态度、土地利用结构信息熵等方法测度昌北山区10年间的“三生”用地演变特征。结果发现,该地区10年间土地利用处于缓慢发展的阶段,但土地利用结构信息熵值不断增加,尤其2015年后人类活动干扰输入的负熵流明显增加,土地利用结构均衡度水平较低,昌北山区的土地利用系统内部结构向无序方向发展。究其原因,与当地工矿业用地扩张、盲目追求生产发展有直接关系。工矿业生产用地的增加会使土地利用系统内部结构无序发展,林草生态用地的增加可以使系统内部更趋于有序状态。分析结果为科学地调节昌北山区“三生”用地关系、探索“三生”良性互动的可持续协调发展之路提供基础研究支持。
Utilizing the current status data of the three issues of land use in the North Mountains of Lin’an Changbei in 2010,2015,and 2020,according to the subjective land use intention of the behavior subject,it is the basis for the division of“Production-living-ecological”land use.The evolution characteristics of“Production-living-ecological”land use in Changbei Mountain Area in recent ten years were calculated according to the transfer matrix of land use,land use change map,single land use dynamic degree,land use structure information entropy and other methods,The results show that the land use is in the stage of slow development,but the information entropy value of the land use structure is increasing year by year,especially after 2015,the negative entropy flow of human activity interference input has increased significantly,the equilibrium level of the land use structure is low,and the internal structure of the land use system in Changbei Mountain Area is developing in a disordered direction.The reason is directly related to the expansion of local industrial and mining land and the blind pursuit of production development:the increase of industrial and mining production land will make the internal structure of the land use system develop disorderly,and the increase of forest and grass ecological land can make the system more orderly.The analysis results can provide basic research support for scientifically adjusting the land use relationship of“Production-living-ecological”in Changbei Mountain Area and exploring the road of sustainable and coordinated development of“Production-Living-Ecological”benign interaction.
