“…The ED scenario simulated the territorial spatial structure of Haikou under high economic growth. Studies showed that the change in living space in Haikou is mainly motivated by economic factors and that living space realizes the maximization of area and growth rate through the massive encroachment of production and ecological space [55]. This human-driven allocation of land resources, which sacrifices ecological and productive space for economic benefits, can boost the economy in the short term, but it will upset the balance between human economic activities and the natural environment in the long term [56,57].…”

“…In areas where agriculture is the main source of income, ESV is mainly influenced by the interaction between production and ecological space [64,65]. The economy of Haikou is primarily service-oriented [51], with associated industries highly reliant on urban living space [55]. The scale and aggregation effect of the service sector could lead to a massive expansion of living space, which will further exacerbate the conflict between land space functions and the decline of ecological functions in the region [66].…”

Structural changes in land use caused by urban development are one of the most important threats to ecosystem services. An in-depth study of the impacts that different land use patterns have on ecosystem service value (ESV) can provide guidance for sustainable urban planning and ecological conservation. In this research, we sought to explore the response mechanisms of ecosystem services under different urban development scenarios from the perspective of “production–living–ecological” space (PLES). This study combined the Patch-generating Land Use Simulation (PLUS) model and ESV equivalent factor method to simulate the PLES and ESV of Haikou in 2035 under three scenarios of business as usual (BAU), ecological conservation (EC) and economic development (ED), and used the spatial superposition method, transfer matrix, and optimized cross-sensitivity analysis to explore the influence of the PLES on ecosystem services. The ESV of Haikou showed a declining trend from 2010 to 2020 under the influence of PLES changes and was at risk of further decline in the future. The reduction in the value of the water supply service constituted a major part of the loss of ESV. The simulation results demonstrated that the EC scenario had the most rational and ecologically efficient allocation of PLES, with the highest ESV and the lowest sensitivity to PLES changes. The results of this research can serve as an important reference for optimizing the urban land use structure and maintaining the stability of ecosystem services.

“…A geochemical approach for seawater intrusion assessment has been conducted by some researchers during last decade (Han et al, 2011;Rao et al, 2011;Agoubi et al, 2013;Garing et al, 2013;Kura et al, 2014;Nair et al, 2015;Eissa et al, 2016;Isawi et al, 2016;Liu et al, 2016;Supriyadi et al, 2017;Kanagaraj et al, 2018;Naseem et al, 2018;Shi et al, 2018;Bahera et al, 2019;Fortuna et al, 2020;Seddique at al. 2019;Dhakate et al, 2020;Sae et al, 2020;Satheeskumar et al, 2020;Telahigue et al, 2020;Wang et al, 2020). A variety of dynamic geochemical processes can also include seawater intrusion into the aquifers.…”

A total of 10 groundwater samples were obtained from groundwater wells with depths of around 8-10 meters distributed around Yogyakarta International Airport, Indonesia to test the geochemical of groundwater for assessing the seawater intrusion. Samples were taken into polyethylene bottles with a volume of 1000 ml. These bottles were rinsed to reduce the risk of any contamination prior to their filing with sampled water. Piper Diagram is used to evaluate seawater intrusion by plotting the percentages of cations and anions (in mEq/L) as a single point on the triangle. The groundwater facies' in the study area are CaHCO3 and CaNaHCO3. It suggests that the origins of the elements Ca and Na were estimated to derive from the dissolution of the plagioclase, hornblende, and pyroxene minerals found in the sand sediment, while the elements of HCO3 were estimated from the dissolution of carbonate minerals or the decomposition of organic matter and root respiration in the soil zone may enrich their concentration. The wells affected by slightly freshening were ZAM-04, ZAM-05, ZAM-06, ZAM-08, and ZAM-10. While the wells that are not affected by the intrusion or fresh were ZAM-01, ZAM-03, ZAM-07, and ZAM-09. However, ZAM-02 well which is close to the coastline and the closest to the airport development area was the only well that affected significantly by freshening, comparing with other wells. Another expected controlling factor was the fault in the northern part which continuously leads that location. By supported a flow pattern or large river, it was concluded the alluvial deposits buried the fault, and it was estimated to continue to that location.
