Understanding the level of human impact on the marine environment requires integrated and ecosystem-based assessment. This research proposes a method based on geospatial modeling at the activity level to assess the potential impact of marine utilization on coastal management and conservation. Laizhou Bay in China was selected as a case study. The research identified the spatial distribution of economic sectors and the potential impact of that distribution on important marine ecological management zones. The findings reveal that, from high to low, threats exist in the bay-head, and to the east and west, and that marine ecological zones are over-used for open mariculture because the environmental impact of this activity is believed to be low. This paper reveals the spatial distribution of threats from a variety of marine-area uses on the ecology of Laizhou Bay. The findings provide support for policymakers in the implementation of marine ecological red-line policy and in the management of the utilization of the marine environment.
了解人类对海洋环境的影响程度需要进行综合的、基于生态系统的评估。本研究提出了一种基于活动层面地理空间建模的方法，以评估海洋利用对海岸管理和保护的潜在影响。选取中国莱州湾作为案例研究。该研究确定了经济部门的空间分布及其分布对重要海洋生态管理区的潜在影响。研究结果表明，从高到低，莱州湾湾顶、东部和西部存在威胁，并且海洋生态区因认为开放式海水养殖活动对环境影响较小而被过度用于此活动。本文揭示了莱州湾各种海洋区域利用对生态的威胁的空间分布情况。研究结果为政策制定者实施海洋生态红线政策和管理海洋环境利用提供了支持。
