“…The island chain has a homogeneous climate condition because of the small spatial scale, that is, a subtropical, oceanic, and monsoon climate with an average annual temperature and rainfall of 17.9°C and 1410.6 mm, respectively (Chi et al, 2019c). The typhoon frequently happens between July and September.…”

“…2) and landscape types by using a visual interpretation method. The landscape types included 10 types and 24 sub-types, which were shown in a previous study by the authors (Chi et al, 2019c). The Landsat 8 data, which possesses multiple spectra, was used to produce various ecological indices through radiometric calibration, atmospheric correction, and band calculation.…”

“…The VP and CP were calculated using the data of landscape types, and the calculation methods for NP, AWMSI, and LII were shown in Chi et al (2019b). Furthermore, a natural ecosystem damaged index (NEDI) was proposed in a previous study by the authors (Chi et al, 2019c). The NEDI could accurately measure the negative effects of human activities based on the landscape types, sizes, levels, and processes, and was also used as a factor of landscape pattern.…”

The vegetation-soil system is fundamental to island ecosystem and changes considerably across sandy and rocky islands due to different natural and anthropogenic factors. An island chain, which is characterized by the coexistence of sandy and rocky islands, the connection of the islands by bridges, and complex influencing factors, was used as the study area. The vegetation-soil system was represented using different indicators and three newly-proposed indices, namely, vegetation health index (VHI), soil health index (SHI), and vegetation-soil system health index (VSSHI). The complex factors were identified in aspects of island basic factors, landscape pattern, terrain condition, and ecological indices. Then, the spatial responses of the system to the factors were analyzed at island and site scales. Results indicated that the vegetation-soil system showed similar and different responses to the complex factors across the dual scales. The similarity was represented by the higher sensitivities of VHI and VSSHI compared with that of SHI at both scales, and the difference mainly indicated that the influences of landscape pattern factors distinctly decreased along the scales from island to site. Island area, sea reclamation proportion, vegetation proportion, and natural ecosystem damaged index were the most important factors at island scale, while the ecological indices showed the highest influences at site scale. The study revealed the spatial characteristics of the vegetation-soil system across different types of islands, clarified the spatial responses of the system to complex factors at the dual scales, and identified the main influencing factors of the system.

“…An island city is an integrated region established according to the requirements of administrative units. An island city consists of island groups, island chains or independent islands along a coastline; inhabited islands compose the main body, with adjacent scattered uninhabited islands [26], [27]. As important links between land and sea, island cities are a key connection in land-and-sea-integrated planning.…”

Vegetation plays a dominant role in and serves as the structural foundation of island-land ecosystems. Island cities, as sea-land ecological complexes, are able to somewhat reflect the general realities of island ecological environments. By using the Landsat series remote-sensing images and an ecosystem service value (ESV) evaluation system, in this paper, the temporal and spatial evolution characteristics of the NDVIs and ESVs of China's 12 island counties over the past three decades are analyzed. According to the research results, (1) The average NDVI of China's island counties dropped from 0.380 to 0.347 in 1990-2018, reflecting a continuous downtrend. The NDVIs of Changhai County and Changdao County show significant changes, with decreases of 45.24% and 37.57%, respectively. (2) The total ESV of China's island counties showed a ''V''-shaped change trend from 1990-2018; the minimum value reached USD 362 million in 2010, then essentially recovered to the 2000 level in 2018. (3) The high and low values of NDVI and ESV in island counties over the years were distributed with the spatial characteristics of high values in the center of the islands and low values at the edges of the islands. The island counties north of the Yangtze River showed the largest changes in NDVI and ESV. (4) Forest cover is the main factor that drives ESV reduction in China's island counties, followed by grassland cover. This study provides an effective method to study the changes in the NDVI and ESV of island cities and proposes the strengthening of island vegetation protection and the promotion of sustainable development in the ecological environments and economies of island cities.INDEX TERMS Spatiotemporal evolution characteristics, ecosystem service values, NDVI, island cities.

Role of Environmentalism in the Development of Green Purchase Intentions: A Moderating Role of Green Product Knowledge

Environmentalism has become not only a significant policy issue but also a crucial topic in marketing research. Environmental consciousness is now considered as a fundamental requirement to prevent further damage to the environment. Efforts have been made to improve the consumers understanding about the environmental consequences of their consumption patterns. This study develops a conceptual model of green purchase behaviour to determine the effects of environmentalism, advertisement message credibility and green perceived value on the consumers’ green purchase intentions with green product knowledge as a moderator. The convenience sampling technique with cross-sectional research design was used to select the sample. Data were collected using survey, and a total of 368 valid questionnaires were used for further analysis. The results from the structural analysis using Smart-PLS depict that environmentalism significantly influences the ad message credibility and green perceived value, and these constructs significantly affect the green purchase intentions. Furthermore, the green product knowledge moderates the relationship between environmentalism, ad message credibility and green perceived value. Overall, the findings of this study extend the theoretical basis of green purchase intentions by empirically testing the proposed model and provides the limitations and further research directions.
