“…The most important functional areas are distributed mostly in the nature reserves in southwestern China with an area of approximately 2,417.26 km 2 . Our results quantified the importance of land use changes to ecological service function (Wu et al, 2021). The change of grassland, water area, and forest land is the main factor affecting ecological service functions.…”

Changes in local land use affect regional ecological services, development planning, and optimal use of space. We analyzed the effects of changes in land use from 2000 to 2025 on the spatial distribution of ecosystem services using CLUS-S modeling to evaluate ecosystem functions in Zhangjiakou, China. We found that the urban ecosystem area in Zhangjiakou increased and farmland decreased between 2000–2025. Water conservation was relatively high and was concentrated in the nature reserves of southern Zhangjiakou. Soil conservation was mainly distributed in eastern and southern counties. The results of the CLUE-S model showed that the relative operating characteristics of the six land use types were > 0.70, and the logistic regression equation was able to successfully explain the distribution pattern of the different types of land use.

“…From 2009 to 2019, the dominant land use transformation in Liyang City was from cultivated lands into aquaculture ponds. Related studies indicate that aquaculture ponds include large areas and rapid growth [ 57 ]. The expansion of aquaculture ponds leads to an increase in total ESVs in Liyang City due to a lower ESV per unit area of the cultivated area than aquaculture ponds.…”

In the context of global food insecurity, a large amount of cultivated land in China has been occupied by aquaculture ponds, leading to a series of variations in the ecological environment. The Chinese government pays close attention to the problem. In order to achieve sustainable development and ensure the safety of China’s cultivated land, the paper uses Liyang City as an example to discuss the spatial characteristics of the expansion of aquaculture ponds through occupying cultivated lands and analyzes the variations in ecosystem service value and cultivated land function. The conclusions are as follows: (1) 2073.24 hectares of cultivated lands were occupied for expanding aquaculture ponds in Liyang from 2009 to 2019, and there was a small number of new aquaculture ponds in the ecological protection area, which shows that the aquaculture ponds in Liyang City are at the stage of disorderly expansion; (2) the total value of ecosystem services increased by 1.43%; supply and support services values decreased, but the increase in regulation and cultural services values was sufficient to more than compensate for the mentioned losses; and (3) the expansion of aquaculture ponds leads to a decrease in the carbon storage of cultivated land, which in turn has negative impacts such as an increase in atmospheric carbon concentration.

Grassland ecosystems resilience to drought: The role of surface water ponds

et al. 2023

Currently, grassland ecosystems' stability is facing severe challenges due to climate variability and the increased frequency and intensity of extreme droughts. In many grasslands worldwide, closed‐basin ponds supply various ecosystem services by collecting rainfall and runoff. These ponds may provide a significant opportunity to mitigate climate change pressures and improve the resilience of grasslands. Nevertheless, their conservation is hampered by problems auditing these small and dynamic features. Understanding the dynamics that characterise the interactions of ponds and grassland vegetation with climate changes is, therefore, a priority for better quantifying future impacts of climate change on managed‐land systems. This study investigated variations of grassland vegetation quality from 2001 to 2021 in Lessinia Regional Park, a pre‐alpine historical rural landscape in northern Italy. We combined multi‐source data, weather information, and satellite‐derived vegetation quality indices. The work focuses the analysis using a ‘pond landscape dominance’ index, calculated as a proxy of hydrologic connectivity, to illustrate the function of ponds in regulating vegetation. We provided an unprecedented mapping of 459 ponds across the whole area. The results show a progressively decreasing vegetation quality in Lessinia, following rainfall and temperature variability. Overall, however, the analysis highlighted the benefit of water extent and closeness to ponds in providing higher resistance of grasslands against drought, especially during the driest study years. These results demonstrate that this approach has great potential for monitoring the resistance of grasslands in response to drought over large regions. This study supports the importance of identifying multiple co‐benefits and ecosystem services related to ponds, which can help communities cope with climate change and environmental challenges.
