“…The patches of these landscape types usually developed in the form of aggregation, resulting in the decrease of landscape pattern heterogeneity, regular shape of patches, and the increase of aggregation among patches. This was similar to previous studies [4,10,74].…”

“…H i describes the degree of hemeroby in landscape type i, which is usually divided into seven grades by researchers [4,37,51,74,75] based on the intensity of human disturbance and seven-point scale. Based on previous researches, experts evaluation and the actual situation of the study area, we divided the landscape types of the study area into seven degrees of hemeroby (Table 2).…”

“…According to the method mentioned above, the hemeroby indexes of the entire area for four target years were calculated. The hemeroby indexes in Daqing were divided into five grades based on the conclusion results and existing reports [4,51,74] (Table 4). The hemeroby indexes of 5559 statistical grids (2.0 km × 2.0 km) were calculated in ArcGIS 10.2 software, achieving that the mean hemeroby indexes of the whole study area were 3.60, 3.71, 3.77 and 3.91 respectively in four target years.…”

Hemeroby is an integrated indicator used to measure the impact and degree of all human interventions on ecological components or ecosystems. The constant exploitation of resources is a strong interference of human beings to the natural environment. With the depletion of non-renewable resources, some cities with resource exploitation as their main industry—“resource-based cities”—are facing great development pressure. In order to quantify the impact of human disturbance on the natural environment and provide some scientific support for policy makers of the resource-based city, we used remote sensing images and landscape pattern metrics, introduced the synthetic hemeroby index model and analyzed the relationship between human disturbance and landscape pattern during 1990–2017. The results showed that: (1) The hemeroby in Daqing continued to rise during 1990–2017, and the main factor was the continuous expansion of the construction land and the reclamation of farmland. (2) In the areas with different hemeroby, there were significant differences in landscape pattern. In the areas with high-level hemeroby, the heterogeneity of landscape pattern was low, the aggregation among patches was high, and the shape of patches was regular, whereas the landscape pattern in the areas with medium-level hemeroby was just opposite. Although the heterogeneity of landscape pattern and the aggregation among patches were high in the areas with low-level hemeroby, the complexity of landscape was low and the shape of patches was regular. (3) In the temporal dimension, the increase of hemeroby contributed to the complexity of patch shape, the decrease of the aggregation among patches, and the fragmentation of landscape pattern. In the spatial dimension, the response in landscape pattern to human disturbance was relatively insensitive in the areas with low-level hemeroby, and this response was basically same in the high-level hemeroby and the whole study areas.

“…A coastal zone is representative of a fragile ecological environment, which is vulnerable to human activities. The intensity of human activities is closely related to the diversity of the coastal landscape and the change of the coastline [17]. The health of ecosystems and the marine environment of coastal zone areas are important issues affecting human survival, and studying the change of surface coverage in coastal zones can provide helpful information for solving this problem.…”

Using remote sensing images of different time phases from 1990 to 2018, the surface coverage information of northern Yantai (coastline, 2 km from coastline to land) was extracted by means of average high tide line and visual interpretation. The end point change rate (EPR) and linear regression rate were used to study the coastline change rate, the fractal dimension of the coastline in the study area was analyzed, and the change of the type of coastal surface cover was analyzed by the transition matrix. The results show that: (1) Form 1990 to 2018, a significant trend of a continuous increase in the total length of coastline was observed with an increase of 181.08 km (43.18%). In the study area, the coastline of Laizhou had the greatest change rate with an EPR value of 33.67 m/a, whereas the coastline of Laishan had the smallest change rate with an EPR value of 0.30 m/a. (2) Over the past 30 years, with the rapid economic development of Yantai and the ensuant urbanization, the total surface area of the coastal zone in the study area has increased by 144.94 km2, mainly in the areas covered by structures and forests/grasses, by 112.96 km2 and 96.08 km2, respectively, while the areas of desert/bare land and water have decreased by 92.26 km2 and 12.32 km2, respectively. (3) The changes among different types in the study area were clear, mainly from desert/bare land, cultivated land, and building areas to forests/grasses cover and structures. The change areas were mainly concentrated in Laizhou, Longkou, Zhifu, and Penglai. Frequent human activities are an important factor affecting the continuous expansion of the coastal areas of Jiaodong Peninsula to the sea. Aquaculture, coastal construction, construction of artificial islands, and expansion of port terminals have seriously affected the sustainability of ecological resources in the coastal areas. At the same time, the changes in the ecological environment in the coastal zone will have a greater impact on the health of the coastal zone.
