摘要
针对海岛土地资源的特殊性,制定了适合于有居民海岛的土地开发利用强度评价流程,给出了有居民海岛土地开发利用强度评价方法,并以东海岛为例,对其2006—2010年的土地资源开发强度进行评价。评价结果分为弱、较弱、中、较强、强和极强6个等级,各等级所占比重分别为94.00%、3.28%、1.98%、0.59%、0.04%和0.11%。评价结果表明,东海岛2006—2010年土地资源总体开发强度较弱。
The aim of this study is to develop the exploitative intensity evaluation for the residential islands,and set the evaluation processes which are suitable for the residential islands on account of land resources specificity.In addition,Donghai Island was taken as an example,while 2006 SPOT images and 2010 ALOS images were used as data sources,and finally,the evaluation on land resources exploitative intensity from 2006 to 2010 was given.The assessment results can be divided into 6 degrees:they are weak,less weak,medium,less strong,strong and extremely strong.Each level accounted for 94.00%,3.28%,1.98%,0.59%,0.04% and 0.11%,respectively.The results show that the land resources exploitative intensity for Donghai Island was less weak from 2006 to 2010.More importantly,the evaluation results can service for the managerial and decision-making departments.
