ABSTRACT Influenced by climate change and human activities, plain terminal lake basins (PTLB) in arid regions experience significant shrinkage, resulting a decline ecosystem services (ESs) such as windbreak sand fixation (SF) habitat quality (HQ). However, systematic assessments of these are limited. A key research challenge is to define enhance the contribution lakes within ESs framework their respective basins. Therefore, this study focused on Ebinur Lake Basin (ELB), Manas River (MRB), Tarim (TRB) Xinjiang. We adopted both InVEST RWEQ models assess regions, employing production possibility frontier (PPF) optimize various ESs, including carbon storage (CS), water yield (WY), HQ, SF. The results indicated general upward trend across basins, with particularly increase CS. Spatial analysis revealed that improved were mainly concentrated mountainous oasis areas most pronounced improvement observed TRB. Within interactions between different exhibited synergistic relationships. notable concave trade‐off relationships existed WY CS, HQ SF, This was largely attributed increased trade‐offs other from widespread agricultural expansion plotted optimal Pareto efficiency curves for three obtain corresponding optimization results, made recommendations enhancement ESs. In summary, lays solid scientific foundation establishing ecological protection boundaries promoting high‐quality sustainable development PTLB areas.

Identifying Conservation Priority Areas of Hydrological Ecosystem Service Using Hot and Cold Spot Analysis at Watershed Scale

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(18), P. 3409 - 3409

Hydrological Ecosystem Services (HES) are crucial components of environmental sustainability and provide indispensable benefits. The present study identifies critical hot cold spots areas HES in the Aglar watershed Indian Himalayan Region using six descriptors, namely water yield (WYLD), crop factor (CYF), sediment (SYLD), base flow (LATQ), surface runoff (SURFQ), total retention (TWR). analysis was conducted weightage-based approaches under two methods: (1) evaluating descriptors individually (2) grouping them into broad ecosystem service categories. Furthermore, assessed pixel-level uncertainties that arose because distinctive methods used identification spots. associated synergies trade-offs among were examined too. From method 1, 0.26% area classified as 3.18% spots, whereas 2 2.42% 2.36% Pixel-level showed 0.57 km2 6.86 consistently respectively, identified 2.30 6.97 respectively. spatial consistent patterns certain parts watershed, primarily south to southwest region, while mainly found on eastern side. Upon analyzing within categories, southern part, scattered throughout especially agricultural scrubland areas. significant synergistic relation between LATQ WYLD, WYLD SURFQ like LATQ, retention, TWR attributed varying factors such land use topography impacting balance watershed. findings underscore need for targeted conservation efforts maintain ecologically sensitive regions at scale.
