Exploring the evolution of vegetation cover and its drivers in Ferghana Basin helps to understand current ecological status analyze changes drivers, with a view providing scientific basis for regional environmental management planning. Based on GIMMS NDVI3g meteorological data, spatial temporal characteristics NDVI were analyzed from multiple perspectives help linear trend Mann–Kendall (MK) test methods using arcgis R language analysis module, combined partial correlation coefficients residual impacts climate change human activities 1982 2015. driving forces. The results showed following: (1) growing season an increasing 34-year period, increase rate 0.0044/10a, distribution was significantly different, which high central part country low northern southern parts country. (2) Temperature precipitation simultaneously co-influenced growth season, most temperature contributing spring, summer being negatively phased positively correlated, fall inhibiting growth. (3) effect main reason overall rapid great variations China, namely change, contributed 44.6% season. contribution 62.32% 93.29%, respectively. study suggests that more attention should be paid role restoration inform ecosystem green development.

Path Analysis on the Meteorological Factors Impacting Yield of Tartary Buckwheat at Different Sowing Dates

Agronomy, Год журнала: 2025, Номер 15(4), С. 950 - 950

Tartary buckwheat is an important characteristic multigrain crop, mainly planted in Sichuan, Guizhou, Yunnan and Tibet, other alpine remote ethnic mountainous areas. In order to clarify the effect of sowing date on yield quality its relationship with meteorological factors The variety Jinqiao No. 2 was used for a two-year trial at Dingxiang Test Base Shanxi Province four dates (15 June, 26 6 July 17 2022 19 30 10 21 2023) starting from bud stage. Responses were investigated by examining growth period structure, yield, component, quality, their climatic factors. results showed that during grain grain-filling stage different when different. Compared times, treatment early mid-July had less than 13.5~27.9 h sunshine, 28.8~48.5 mm rainfall, more 10.5~19 days ≤15 °C days, but most serious low-temperature stress (≤15 up 27 days). 69.8~77.0% 69.9~79.1% lower June 2023 respectively, later yield. Delayed beneficial accumulation flavonoids protein grains, average value 11.55% 14.64% higher first sowing, content fat starch significantly reduced. result path analysis low temperature days) solar radiation duration key points attaining high due mean daily flowering maturity negative 1000-seed weight, seed setting rate, crude lipid buckwheat, direct sunshine flavonoid greatest. sown treatments, because avoiding long rainy sunless weather filling stage, which enabled blossoming normally finally attained

Seasonal precipitation distribution determines ecosystem CO₂ and H₂O exchange by regulating spring soil water–salt dynamics in a brackish wetland

Abstract The intensification of the global hydrological cycle is anticipated to increase variability precipitation patterns. Brackish wetlands respond changes in patterns by regulating absorption and release CO 2 H O maintain stability ecosystem functions. However, there limited understanding how inter‐seasonal distribution (SPD) affects exchange compared with annual totals. Here, we conducted four consecutive years field experiments a brackish wetland, manipulating proportion across different seasons while maintaining constant total. We utilized five inter‐SPD proportions (+73%, +56%, control (CK), −56%, −73%) examine effects SPD on exchange. Our findings revealed that fluxes showed trend decreasing decrease spring distribution. Among them, net exchange, evapotranspiration, carbon use efficiency water were shown be more sensitive summer autumn This negative asymmetric response pattern suggests primarily governed seasonal variability, soil water–salt dynamics identified as key driver. Therefore, this association can explained fact drought early growth stage exacerbates salinization inhibits vegetation colonization growth, thereby greatly impairing –H capacity wetlands. results emphasized extreme precipitation‐induced conditions will influence future. These are crucial for improving predictions sequestration water‐holding Read free Plain Language Summary article Journal blog.
