“…The Chishui River, a first-class tributary of the upper reaches of the Yangtze River, originates in Zhenxiong County, Yunnan Province, and is the only tributary of the Yangtze River in China that has not been dammed. The Chishui River serves as an important ecological barrier and water conservation site in the upper reaches of the Yangtze [29]. The Chishui River Basin is located in the bordering areas of Yunnan, Guizhou and Sichuan provinces, spreading over 13 counties and cities of the three provinces (Figure 1).…”

“…The Chishui River Basin (27 • 20 -28 • 50 N, 104 • 45 -106 • 51 E) is rich in natural resources and biodiversity, harboring many wild plants and animals categorized as China's rare or endangered species, and functions as an essential component of the ecological barrier in the middle and upper reaches of the Yangtze River [29]. However, in the past decades, large population size, rapid urban development and increasing human pressure has posed serious challenges to the regional environment, and the conflict between economic development and environment protection has been intense.…”

“…In recent years, the severe ecological and environmental problems in the region have attracted extensive attention from scholars. They have studied the ecological status of the Chishui River basin in terms of hydrological ecology [30,31], ecosystem services [29], landscape pattern [32], and vegetation cover [33], yet studies on the long-term detection of ecological and environmental quality in the Chishui River basin are relatively limited. The present study aims to analyze spatial and temporal changes in regard to the eco-environmental quality of the basin, and is thus important for the future ecological protection and management of the basin.…”

The Chishui River Basin is located in the bordering area of Yunnan, Guizhou and Sichuan provinces, which serves as an important ecological barrier in the upper reaches of the Yangtze River, and plays a leading role in preserving natural environments, protecting water resources, and maintaining soil functions. However, the eco-environmental quality in the basin has encountered serious challenges in recent years, and the conflict between eco-environmental protection and economic development becomes increasingly prominent. Therefore, it is particularly important to quantitatively assess the extent of the eco-environmental changes in this basin. The present study acquired Landsat series remote sensing images based on the Google Earth Engine (GEE) platform, constructed a remote sensing ecological index (RSEI) as the assessment index that reflects the eco-environmental quality using principal component analysis, studied the changing trend in the eco-environmental quality using the Sen–Mann–Kendall trend test, analyzed the spatial clustering distribution patterns of the eco-environmental quality, based on spatial autocorrelation analysis, and applied the geographical detector model to determine the impacts of natural and anthropogenic factors on the eco-environmental quality. We further applied the CA–Markov model to simulate and predict the eco-environmental quality of the basin in 2025. The results showed the following: (1) between 2000 and 2020, the eco-environmental quality of the Chishui River Basin had been greatly improved. The average RSEI value increased from 0.526 in 2000 to 0.668 in 2020, and the percentage of areas belonging to the good or excellent quality category increased from 42.65% to 68.48%. (2) The main drivers of the eco-environmental quality included population density, mean annual temperature, land use type and elevation. The interactive effect between these drivers was significantly higher than that of individual drivers, and thus possessed stronger explanatory power for quality differences. (3) It is predicted that in 2025, the eco-environmental quality of the basin will continue to improve, and the proportion of land areas with good or excellent quality will continuously increase. The present study can provide reference value for local environmental protection and regional planning.

“…Studies demonstrate alternative food production methods that can reduce the impacts of agriculture on ecosystems and thus enhance productive capacity over time, strengthening ecosystem services (Chen et al 2022; Puech e Starkb 2023). Based on an environmentally sustainable approach, with a focus on food security, human health, and social and economic well-being ( Building upon this approach, studies show that the use of shade trees in agroforestry systems offers the possibility to mitigate extremes in terms of temperature, humidity, and other microclimatic variables (Lin 20007;Glazle et al 2021;Wang et al 2022). Such adaptations in agricultural areas are important for mitigating the annual changes that arise in the climate, thus ensuring food production.…”

One possible way to make agricultural systems more sustainable is to mimic natural ecosystems. In this regard, syntropic agroforestry systems are agroecosystems that imitate, to some extent, the structure and natural dynamics of forests. This study aims to address the following question: Are SAS microclimatically similar to tropical forests? To investigate, climate variables such as canopy coverage, relative air humidity, air temperature, soil temperature, and illuminance were measured in both a tropical forest area and an adjacent Syntropic Agroforestry System. The results showed significant differences in relative humidity, air temperature, and illuminance compared to the forest. These differences may be attributed to the higher density of tree individuals and the number of strata, which are greater in the tropical forest compared to the syntropic agroforestry system. It is concluded that, despite resembling a tropical forest in appearance, syntropic agroforestry systems do not have microclimatic conditions similar to tropical forests.

“…However, the water yield ecosystem service function varies widely among different regions due to differences in responses to precipitation, evapotranspiration, LULC, and topography ( Xie et al, 2017 ). Few previous studies have attempted to examine the effects of these climatic factors, land use patterns, and topographic factors on water yield in alpine-gorge areas with a complex topography, diverse climate types, and a fragile ecological environment ( Luo et al, 2021 ).…”

Water yield is an ecosystem service that is vital to not only human life, but also sustainable development of the social economy and ecosystem. This study used annual average precipitation, potential evapotranspiration, plant available water content, soil depth, biophysical parameters, Zhang parameter, and land use/land cover (LULC) as input data for the Integrated Valuation of Ecosystem Service Tradeoffs (InVEST) model to estimate the water yield of Shangri-La City from 1974 to 2015. The spatiotemporal variations and associated factors (precipitation, evapotranspiration, LULC, and topographic factors) in water yield ecosystem services were then analyzed. The result showed that: (1) The water yield of Shangri-La City decreases from north and south to the center and showed a temporal trend from 1974 to 2015 of an initial decrease followed by an increase. Areas of higher average water yield were mainly in Hutiaoxia Town, Jinjiang Town, and Shangjiang Township. (2) Areas of importance for water yield in the study area which need to be assigned priority protection were mainly concentrated in the west of Jiantang Town, in central Xiaozhongdian Town, in central Gezan Township, in northwestern Dongwang Township, and in Hutiaoxia Town. (3) Water yield was affected by precipitation, evapotranspiration, vegetation type, and topographic factors. Water yield was positively and negatively correlated with precipitation and potential evapotranspiration, respectively. The average water yield of shrubs exceeded that of meadows and forests. Terrain factors indirectly affected the ecosystem service functions of water yield by affecting precipitation and vegetation types. The model used in this study can provide references for relevant research in similar climatic conditions.
