摘要

在沿岸生态系统中,海草草甸在提供生态系统服务(如提供、控制和支持)方面发挥着至 关重要的作用。然而,该生态系统是沿海环境中最受威胁的生态系统之一,由于人为干扰和环境的快速变化,该生态系统已经退化。此外,海草草甸的范围尚不清楚,草甸的健康状况也没有得到监测和记录。有关卡里蒙查瓦国家公园海草范围和健康状况现状的信息很少。我们根据生态质量指数对印度尼西亚哲帕拉卡里蒙查瓦国家公园的海草丰度、状态和健康状况进行了评估。该地区拥有广阔的海草草甸,但受到该地区工业/旅游区扩张的影响。本研究旨在根据生态质量指数评估海草的现状。结果显示,卡里蒙查瓦国家公园的海草范围总面积为 969.15 公顷,其中发现了 7 个物种,包括 Enhalus acoroides、Thalassia hemprichii、Cymodocea rotundata、Cymodocea serrulate、Halodule pinifolia、Halophila ovalis 和 Halodule uninervis。海草草甸覆盖率为中等,被归类为不太健康。海草生态质量指数值为 0.66,表明卡里蒙加瓦国家公园的海草状况为中等。影响海草状况的生态因素是附生植物覆盖率和大型藻类覆盖率。

Evaluating the seagrass ecological condition and habitat extent in Karimunjawa National Park, Jepara Indonesia
In the coastal ecosystem, seagrass meadows play a vital role in delivering ecosystem services such as provision, control, and support. However, this ecosystem is one of the most threatened in the coastal environment, and it has been degraded as a result of anthropogenic disturbance and rapid environmental changes. Furthermore, the extent of the seagrass meadows is unknown, and the health of the meadows is unmonitored and unrecorded. There is little information on the current state of the seagrass extent and health conditions in Karimunjawa National Park. We evaluate the abundance, states, and health conditions of the seagrass meadows based on the ecological quality index in Karimunjawa National Park, Jepara, Indonesia. This district has a vast extent of seagrass meadows but has been affected by the expansion of the industrial/tourism area within the region. This study aimed to assess the seagrass current condition based on the ecological quality index. The result showed that the total seagrass extent area in Karimunjawa National Park was 969,15 ha where seven species were found in this area, including Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Cymodocea serrulate, Halodule pinifolia, Halophila ovalis and Halodule uninervis. Seagrass meadow coverages were moderate and categorized as less healthy. The seagrass ecological quality index value was 0.66 which indicated that the seagrass condition in Karimunjawa National Park was moderate. Ecological factors that affect the seagrass state are epiphyte cover and macroalgal cover.
