“…The TLB (30 • 7 19"-32 • 14 56" N, 119 • 3 1"-121 • 54 26" E) is the core area of the Yangtze River Delta, which is located in the lower portion of the Yangtze River (Figure 1). It has an area of approximately 36,900 km 2 , with a complex river network and numerous lakes, of which the river density is about 3.4 km/km 2 [53].…”

“…It has an area of approximately 36,900 km 2 , with a complex river network and numerous lakes, of which the river density is about 3.4 km/km 2 [53]. There are more than 200 rivers and 9 lakes with an area over 10 km 2 in the basin, whereby the Taihu Lake (2427.8 km 2 ) is the largest lake in the basin and the third largest freshwater lake in China [54]. The average elevation of the TLB is 34.4 m, and there are two types of terrains in the TLB-mountains and plains.…”

Habitat quality (HQ) is of great significance to regional sustainable development, which is a key link for regional ecological security and human welfare. Assessing the temporal and spatial evolution of HQ caused by land-use change could provide a scientific basis for regional ecological protection and land management. Here, based on the ArcGIS platform and the InVEST model, this study quantified the spatial and temporal evolutions of land use, landscape patterns, and HQ from 1985 to 2015, in Taihu Lake Basin (TLB). Hotspot analysis tools were used to identify the spatial agglomeration and evolution characteristics of HQ in TLB. The results showed that, (1) the land use and landscape pattern in TLB experienced dramatic change process during 1985–2015, with the dominating conversion being from farmland to construction land, which led to an increase in landscape heterogeneity and fragmentation. (2) The HQ was generally reduced in the past 30 years. In particular, the decline of HQ was extremely severe in the peripheral area of cities and roads, due to urban sprawl. (3) Regarding the spatial distribution of HQ, the northern and eastern areas were generally higher, while the western and southern areas were generally lower. The hotspots areas were mainly located in the southwestern mountain area and west-central lake area, while the cold spots areas were mainly located in urban areas in the north and the east. (4) The area and degree of habitat degradation were both increased significantly due to land-use change, and the degradation of the Taihu Lake was highlighted. Strengthening the ecological environment management and reducing the threat of urban expansion to the HQ is urgently required. This study could help understand HQ of the TLB and provide a scientific basis for decision-makers.

“…TLB has a lake area totaling 3160 km 2 (based on the surface area of lakes > 0.5 km 2 in area), which account for 10.7% of the basin's plain area. There are 10 lakes with an area of more than 10 square kilometers, while Taihu Lake (2427.8 km 2 ) is the largest freshwater lake in the basin and the third largest freshwater lake in China [25]. Figure 2 shows the general framework for assessing how urban expansion influenced multiple ecosystem services (ESs) in the Taihu Lake Basin from 1990 to 2010.…”

Urban expansion poses severe threats to ecosystems. It is therefore important we better understand the impact of different urban expansion level on ecosystems for developing regionally differentiated ecological protection policies. Here, we proposed a conceptual framework to describe the impacts of urbanization on bundles of ecosystem services. Referred to as the concept of land use degree by nighttime light data, we put forward and verified an urban expansion level model. According to this model, study area was divided into a slow increase zone, increase zone, and rapid increase zone. Then, taking Taihu Lake Basin in China as a case, we used Zonal-statistics and Pearson correlation coefficients to reveal the impact in different zones of urban expansion level on multiple ecosystem services: crop production, freshwater supply, aquatic production, net primary productivity, soil conservation, water retention, flood regulation, and forest recreation index. Our results revealed that urban expansion levels significantly impacted all ecosystem services. In either increase zone or rapid increase zone, we found lowered values of crop production, net primary productivity, soil conservation, water retention, and flood regulation, while both aquatic production and forest recreation index increased in all zones from 1990 to 2010. Across the levels of urbanization, urban expansion level was always negatively correlated with provisioning services. This result suggests local governors should improve crop production per unit area and increase the cultivated land area to guarantee food security. In addition, urban expansion level had positive correlations with the trade-offs between flood regulation and forest recreation index, and those among crop production, freshwater supply, and net primary productivity. Therefore, policy-makers should effectively maintain the land use balance among ecological protection, agriculture development, and urban expansion to better coordinate relationships between development and protection. In acquiring quantitative knowledge of how urban expansion level drives ecosystem changes, our findings may help guide future sustainable urban planning with respect to ecosystem services, urban development, and human welfare benefits.

“…Relationships among regulating services are characterised by either trade-offs or synergies across the studied literature. Synergies seem to occur primarily in forested areas (Maes et al 2012, Qiu and Turner 2013, Mouchet et al 2017, Kong et al 2018); however, nutrient regulation and global climate regulation appeared to have had a substantial opposite effect in two studies (Bai et al 2011, Alamgir et al 2016) Qiao et al (2018). found that, although regulating services were generally associated in the Taihu Lake Basin (China), trade-offs also occurred between flood regulation and carbon storage/water retention 7(Qiao et al 2018).…”

Background: the concept of 'ecosystem services bundles', i.e. ecosystem services that repeatedly appear together across space and/or time, has been developed and refined as part of an integrated approach to assess interactions between ecosystem services. Nevertheless, published evidence of actual use of bundles in decision-making is lacking. In the light of this gap, a review of what bundle approaches have shown and what they can bring to decision-making is timely. Method: we conducted two separate systematic reviews. The first one addressed emerging issues within what we identify as the diverse utilisation and definition of the concept of 'bundle' in the literature. The second one focused on papers dealing with bundles as sets of consistently associated services. Review Synthesis: the review first highlights that the confusion surrounding the term 'bundle' in ecosystem services literature threatens to weaken the potential for analysis of bundles to inform decision-making. Then, thanks to the review of peer-reviewed papers that detect bundles as sets of consistently associated services, we analyse the diversity of methodological choices and we detail the interactions observed between different ecosystem services across the literature. We also show that landscape features, socio-economic conditions and institutional factors are all potential drivers for the occurrence of specific bundles in a landscape. Discussion: overall, it appears that the analysis of bundles provides an opportunity to enhance policy effectiveness. Nevertheless, the methodological challenges linked to the identification and interpretation of bundles call for careful and reflective study designs. We anticipate that this review will lead to a better understanding by scientists and practitioners of the potential for bundle studies to inform decision-making.
