| 摘 要： | 为探究锦州湾海域围填海的空间开发及利用程度，选取了1995~2015年间的5期Landsat TM、ETM+、OLI遥感影像作为基础数据，对该区域围填海的空间利用结构、利用水平、动态度及质心转移进行了分析，结果如下:（1）锦州湾海域空间开发利用活动类型多样，但结构规模不均衡，总围填海面积由1995年的2756.93 hm2增加到2015年的7234.70 hm2，以中部海域港口用海增加面积最大，南部海域围填未开发用海次之。（2）在空间利用水平方面，中部海域人工岸线比例最高，北部海域变化不大，南部海域在2010年以后增长较快；用海类型多样性指数方面，中部海域在2005年前较高，用海类型较合理，2010年及以后不断下降，北部海域波动较小，南部海域呈缓慢上升趋势。（3）围填海利用的动态度方面，北部海域港口用海动态度最高，达到5%；中部海域，围填养殖用海动态度变化最大，为7.54%；南部海域围填未开发利用动态度为5.94%。（4）围填海的空间质心转移方面，1995~2015年间围填海质心不断向东南方向移动，说明锦州湾海域的围填海开发逐渐向东南迁移。

| Abstract: | To explore the space development and utilization degree of reclamation in Jinzhou bay, we chose a total of 5 base of TM, ETM + data from 1995~2015 as basic data, and analyzed the spatial utilization structure, utilization level, dynamic attitude and center of mass transfer of the enclosed sea.The results show that(1) Jinzhou bay waters space development and utilization of the activity type, but the scale structure is not balanced, the total reclamation area from 2756.93 hectares in 1995 to 7234.70 hectares in 2015, in the central sea port with the sea area of the largest increase, the southern waters of undeveloped sea time.(2) In terms of spatial utilization, the proportion of artificial coastline in the central sea area is the highest, and the northern waters have not changed much, and the southern seas have increased rapidly since 2010.From sea type diversity index, the central sea 2005 years ago in Marine diversity index is higher, more reasonable types with the sea, and later in 2010, with the sea type diversity index decreased, northern waters less volatile, southern waters slowly rising trend.(3) With the attitude of reclamation, the northern sea ports have the highest sea movement attitude, reaching 5%;In the middle of the sea, the change in the sea moving attitude was the largest in the surrounding area, which was 7.54%.In the southern sea, the undeveloped attitude was 5.94%.(4) The spatial center of the reclamation of the sea was transferred, and the reclamation of the sea center in 1995~2015 kept moving to the southeast, indicating that the reclamation of the waters of Jinzhou Bay was gradually moving to the southeast. |
