Summary

This summary is machine-generated.

Coastal zone spatial benefits in Fujian fluctuated, influenced by marine climate changes like sea level rise. Seawater salinity showed the strongest correlation, supporting sustainable coastal development.

Area Of Science

  • Environmental Science
  • Marine Science
  • Socio-economics

Background

  • Coastal zones are critical interfaces between land and sea, requiring integrated management for sustainable development.
  • Understanding the interplay between coastal ecosystems, economic activities, and climate is vital for effective protection strategies.

Purpose Of The Study

  • To develop a spatial benefit evaluation system for coastal zones, integrating terrestrial and marine dimensions.
  • To analyze the impact of marine climate evolution on coastal zone spatial benefits in Fujian Province, China.
  • To investigate correlations between marine climate variables and coastal spatial benefits.

Main Methods

  • Constructed a spatial benefit evaluation system encompassing ecological, economic, and social dimensions.
  • Employed entropy, moving average, and Mann-Kendall trend tests for quantitative analysis.
  • Utilized grey relational analysis to determine the correlation between spatial benefits and marine climate.

Main Results

  • Coastal zone spatial benefits in Fujian showed a fluctuating trend (increase then decrease) from 2005-2020.
  • Marine climate changes, including sea level and tropical cyclone activity, aligned with global warming trends.
  • Seawater salinity exhibited the highest correlation with coastal zone spatial benefits, while tropical cyclones had the weakest.

Conclusions

  • The economic system's contribution to enhancing spatial benefits was limited.
  • Marine climate significantly impacts coastal zone spatial benefits, with seawater salinity being a key factor.
  • Findings support evidence-based strategies for sustainable coastal zone management and development.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment 01:17

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Adaptations that Reduce Water Loss 01:57

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...

Global Climate Change 01:50

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
