【摘要】：基于生態(tài)系統(tǒng)管理理論,從海洋投入強度、海洋利用強度、海洋經濟效益及海洋生態(tài)環(huán)境質量層面,構建海域集約利用評價的指標體系,運用模糊決策分析理論計算各指標權重,得到河北省沿海地級市2005—2014年的海域集約利用綜合指數,并利用聚類分析法及協(xié)調度指數對河北省海域集約利用的區(qū)域差異特征進行了分析。研究結果表明:2005—2014年河北省海域集約利用綜合水平不斷提高,除海洋生態(tài)環(huán)境質量準則層指數呈下降趨勢外,海洋投入強度、海洋利用強度、海洋經濟效益3個層面指數均呈上升趨勢,其中持續(xù)增加趨勢最明顯的是海洋經濟效益準則層;河北省沿海三市海域集約利用綜合指數及各準則層指數的時序變化特征基本一致,但各區(qū)域之間仍體現著不同的變化特點,滄州市海域集約利用程度較高,唐山市海域集約利用經歷了由低到高的過程,秦皇島市海域集約利用的狀況整體處于一般水平;河北省及沿海三市海域集約利用總體保持了較高的協(xié)調度,但各地區(qū)不同時段的變化特征有所不同。
[Abstract]:Based on the theory of ecosystem management, the index system of sea area intensive utilization evaluation is constructed from the aspects of ocean input intensity, ocean utilization intensity, marine economic benefit and marine ecological environment quality. By using fuzzy decision analysis theory to calculate the weight of each index, the comprehensive index of intensive utilization of sea area in coastal cities of Hebei Province from 2005 to 2014 is obtained. Cluster analysis and coordination index were used to analyze the regional differences of intensive utilization in Hebei Province. The results show that the comprehensive level of intensive utilization of sea area in Hebei Province from 2005 to 2014 has been continuously improved. In addition to the decreasing trend of the layer index of marine ecological environment quality criterion, the intensity of ocean input and the intensity of ocean utilization are also shown. The three indexes of marine economic benefit are all on the rise, and the most obvious increasing trend is the criterion layer of marine economic benefit. The temporal variation characteristics of the comprehensive index of intensive utilization and the index of each standard layer in the three coastal cities of Hebei Province are basically the same, but different characteristics still exist among the different regions, and the intensive utilization of Cangzhou sea area is relatively high. The intensive utilization of the sea area in Tangshan City experienced a process from low to high. The situation of intensive utilization of the sea area in Qinhuangdao City was generally at a general level; the intensive utilization of the sea area in Hebei Province and the three coastal cities overall maintained a high degree of coordination. However, the variation characteristics of different periods of time vary from region to region.
