With its unique geographical location, the coastal zone has concentrated great advantages in resources, population and economy. However, with the deepening of marine resources development activities, a series of problems have emerged in the coastal zone, such as the gradual shortage of resources, the decline of environmental quality and the increase of ecological risks. The coastal zone ecosystem has shown a certain degradation trend. Maintaining the health of the coastal zone ecosystem has become the primary task of the sustainable development of the marine economy. Monitoring the coastal ecosystem carrying capacity, diagnosing the health status of the coastal ecosystem, effectively planning and managing the development and utilization of natural resources in the coastal zone, and controlling human activities related to the sea within the ecological carrying capacity and health limits of the coastal zone are of great significance to the sustainable development of society and economy in the coastal zone. In this study, the ecosystem health model, state space model and ecological health early warning principle were comprehensively applied to construct the coastal ecosystem health diagnosis framework of “Carrying type →Early warning degree →Health level;” The evaluation index system of coastal ecosystem carrying capacity was established; Taking Shandong Province as the empirical research object, the health status of the coastal ecosystem in Shandong Province was diagnosed by using the relevant data from 2007 to 2019. The empirical results show that: (1) From 2007 to 2013, the carrying capacity of the coastal ecosystem in Shandong Province was relatively good, in the state of “loadable” or “critical overload,” while from 2014 to 2019, the carrying capacity was poor, in the state of “overload;” (2) From 2007 to 2013, the early warning degree of coastal ecosystem health in Shandong Province was in the state of “no alarm,” “light alarm,” and “medium alarm,” and the health level was in the state of “very healthy,” “healthy,” and “sub-health;” from 2014 to 2019, the health warning level of the coastal ecosystem in Shandong Province was in the state of “serious alarm” and “extremely serious alarm,” and the health level was in the state of “unhealthy” and “Morbid,” and the health status was worrying; (3) The key influencing factors affecting the carrying capacity of the coastal ecosystem mainly included the output of marine mining, marine GDP, per capita marine production, total amount of main pollutants directly discharged into the sea, domestic tourist arrivals in coastal cities, area of marine nature reserves, proportion of class IV and inferior class IV seawater, average density of beach garbage in the monitoring area, number of medical and health institutions; Finally, some policy suggestions were put forward to improve the health of coastal ecosystem in Shandong Province. In the “discussion” part of this study, the consistency between the research results of this paper and the actual situation of the marine ecosystem in Shandong Province and the existing research results of the same kind is compared, and the applicability and limitations of the research methods in this paper are put forward, indicating that the research methods in this paper are more applicable to the comparative analysis under the same ideal value determination criteria.

“…Therefore, economically, healthy coral reefs and their live inhabitants can be a source of livelihood in, among others, capture fisheries. However, coral reef ecosystems are vulnerable to damage and extinction resulting from natural and anthropogenic factors (Sukmara et al, 2001;Sudiono, 2008;Prasetya et al, 2018). The natural factors are sea surface temperature rise, earthquakes, tsunamis, and acidification, while the anthropogenic factors may involve environmental pollution, unsustainable fishing (e.g., blast fishing and trawling), and water tourism that are not environmentally friendly (Bravo et al, 2021).…”

Highlight ResearchPoint Intercept Transect Method (PIT) and Underwater Photo Transect (UPT) to monitor coral cover was comparedPercentage of hard coral cover was analyzedThe average difference of the percentage of hard coral cover obtained from the PIT and UPT was analyzed AbstractCoral reef ecosystems are vulnerable to damage and extinction. Therefore, it is imperative that, as part of conservation, their conditions are monitored using straight forward or easy-to-use methods. The research was intended to compare the effectiveness of using Point Intercept Transect (PIT) and Underwater Photo Transect (UPT) methods in calculating percent hard coral covers. It was conducted at six sites in Karimunjawa Islands, Indonesia: Cemara Besar, Cemara Kecil, Taka Malang, Tanjung Gelam, Menjangan Besar, and Menjangan Kecil. At each site, photographs of coral reefs were taken in two ranges of depths, shallow (3–6 m) and deep (9–12 m), along the length of the predefined transects (100 m for PIT and 50 m for UPT). In UPT, the photos were taken using a 58 x 44 cm frame. Fifty photo frames were collected then processed using Coral Point Count with Excel extensions (CPCe) 4.1. The results showed that PIT and UPT produced different percentages of hard coral cover at each site, with the most significant difference found in deep waters of Menjangan Besar (45.27%) and the least one in deep waters of Menjangan Kecil (0.08%). Overall, the difference in percent covers was averagely 9.79 percentage points, which is still categorized into small. Both methods have their own advantages and disadvantages. However, UPT is preferable because its results can be reanalyzed, especially the identified coral reef species.

Introduction Tourism has a major role in economic and social interests. Karimunjawa is one of Indonesia’s tourist destinations, making the Karimunjawa Island a national park area for tourist destinations. Indonesia must have policies to support tourism, transportation, and infrastructure. This research aimed to identify the role of the community, tourists, NGOs, and district governments in implementing the Karimunjawa National Park management policy. Material and methods The descriptive quantitative method (questionnaire and path analysis) was used in this research. Results The test results showed that there was a direct relationship between the role of the community and the Central Java provincial government with a Path Coefficients value of 0.515; the role of tourists in government policies was −0.230, the role of NGOs in Central Java Provincial Government policies with a Path Coefficients value was 0.292 and the role of district governments against the Provincial Government policy was −0.332. Conclusions The value of Path Coefficients showed that there was still a lack of policy implementation from the provincial government to the community and NGOs. Collaboration between the district and provincial governments in managing was an effective way of monitoring tourism sustainably.
