“…In recent years, the impact and pressure of China's urbanization on the ecological environment have become more and more obvious [64]. Urban expansion takes up a large amount of ecological land and production land, which reduces the surface vegetation coverage [65], increases the impervious surface area, and intensifies the urban heat island effect [28,55].…”

Over the last few years, under the combined effects of climate change and human factors, the ecological environment of coal mining areas has undergone tremendous changes. Therefore, the rapid and accurate quantitative assessments of the temporal and spatial evolution of the ecological environment quality is of great significance for the ecological restoration and development planning of coal mining areas. This study applied the ecological environment index after topographic correction to improve the remote sensing ecological index (RSEI). Based on a series of Landsat images, the ecological environment quality of Yangquan Coal Mine in Shanxi Province from 1987 to 2020 was monitored and evaluated by an improved remote sensing ecological index. The results show that after topographic correction, the topographic effect of the remote sensing ecological index was greatly reduced, and its practicability was improved. From 1987 to 2020, the ecological environment quality of Yangquan Coal Mine was improved, and the mean of the RSEI increased from 0.4294 to 0.6379. The ecological environment quality of the six coal mines in the study area was improved. Among the six coal gangue dumps, the ecological environmental quality of D1, D2, D3, and D4 has improved, and the ecological environment quality of D5 and D6 worsened. The percentages of improved, unchanged, and degraded ecological environment quality in the entire coal mining area were 77.08%, 0.99%, and 21.93%, respectively. The global Moran’s index was between 0.7929 and 0.9057, and it was shown that there was a strong positive correlation between the ecological environmental qualities of the study area, and that its spatial distribution was clustered rather than random. The LISA cluster map showed that the aggregation and dispersion degree of ecological environment quality was mainly high–high clustering and low–low clustering over the whole stage. During the study period, temperature and precipitation had limited impacts on the ecological environment quality of Yangquan Coal Mine, while the coal mining activities and urbanization construction seriously affected the local ecological environment quality and the implementation of ecological restoration policies, regulations, and measures was the main reason for the improvement of the ecological environment quality.

“…Shen Ge et al proposed WDCI for wetland destruction [17]; Yang et al added a parameter to measure the health of vegetation on the basis of RSEI, and proposed the CEEI index [18]. Among them, the RSEI model is widely used in regional ecological environment assessment and monitoring due to its strong comprehensiveness, simple data acquisition, and high degree of data visualization [19] [20] [21] [22].…”

This research is based on Landsat5 TM, Landsat8 OLI/TIRS remote sensing data using RSEI model to analyze and monitor the ecological environment and its temporal and spatial changes in the forest-grass transition zone in Northeast China from 2004 to 2019. The change characteristics of the ecological environment of different types of land cover types are monitored by RSEI method, and the response of different land cover types to natural factors such as precipitation and temperature is analyzed at the same time. The distribution of RSEI in the study area presents the characteristics of high in the east and low in the west. The eastern mountainous area is densely covered with woodland, which is the area with the best ecological environment quality in the study area. The grassland in the western plain and the saline-alkali land around the river are the areas with poor ecological environment in the study area. Climate, precipitation, topography and other natural elements work together to form the quality of the ecological environment in the study area roughly bounded by 120˚E. In years with poor natural conditions, this dividing line will have a clear eastward shifting trend, especially in the northern part of the study area. The spatial distribution of RSEI in the study area has a high degree of spatial autocorrelation, and Global Moran's I has been above 0.8 over the years. In terms of temporal changes in ecological conditions, the ecological environment in the study area was basically stable from 2004 to 2008, with a slight deterioration; it improved significantly from 2008 to 2011; however, it deteriorated significantly from 2011 to 2019. According to the results of partial correlation analysis, the ecological environment of the former is highly correlated with natural elements such as climate and precipitation, while the latter is mainly affected by human factors.

“…Coastal zones not only ensure a suitable ecological environment but also abundant marine products (Trung Thanh et al, 2021), and the strategic position of coastal zones in the world is also increasingly prominent (Yu et al, 2010;Islam and Shamsuddoha, 2018;Rojas et al, 2019). However, the burgeoning of the marine economy in coastal areas has also caused damage to coastal ecologies (Sievers et al, 2020;Zheng et al, 2020;Yu et al, 2021).…”

“…Many coastal areas are developing and utilizing marine resources on a large scale to rapidly develop the marine economy. Humans have also carried out large-scale and unrestrained development of coastal resources, which has led to serious damage and deterioration of coral reefs, mangroves and other coastal ecosystems, seriously restricting the sustainable development of the coastal ecology and social economy (Das, 2017;Kim et al, 2020;Zheng et al, 2020). For advocating ecological environmental protection in today's society (Rao et al, 2018), coastal zones provide valuable production and living space for human beings worldwide, and the strategic positions of coastal zones are becoming increasingly prominent worldwide (Yu et al, 2010;Islam and Shamsuddoha, 2018;Rojas et al, 2019).…”

What Are the Impacts of a Coastal Zone Protection Policy on Farmers’ Livelihood Capital? Empirical Analysis From the Perspective of Farmer Participation

et al. 2021

To restore and protect the ecosystem service function of coastal zones, some farmers have changed their certain original production methods and lifestyles and some have even relinquished a portion of the economic benefits that could be obtained directly. What impacts do the coastal zone ecological protection policies bring to the livelihoods of coastal farmers? The strict coastline protection of Beibu Gulf, Hepu County, Beihai City, Guangxi Zhuang Autonomous Region, China, is taken as an example. Combined with the sustainable livelihood framework (SLF), this paper set up an evaluation index system for the livelihood capital of farmers in the Beibu Gulf coastal zone, obtaining 568 valid questionnaires through a field survey, and use the propensity score matching and difference-in-difference (PSM-DID) method to study the impacts of a coastal ecological protection policy on the livelihood capital of coastal farmers from the perspective of farmer participation. The results show that (1) the coastal ecological protection policy had a significant impact on the natural capital and social capital of coastal farmers that actively participated in coastal ecological protection, which increased by 0.181 and 0.052, respectively. (2) However, it did not have a significant impact on the total livelihood capital, human capital, physical capital or financial capital. Therefore, this paper presents policy suggestions for constructing coastal ecological compensation mechanisms and for promoting active participation by coastal farmers in coastal ecological protection efforts.
