In order to understand the mechanism of water uptake by vegetation, we propose a vegetation-water model with nonlocal effect which is characterised delay strong kernel in this paper. By mathematical analysis, condition producing steady pattern obtained. Furthermore, amplitude equation determines type Turing obtained nonlinear analysis method. The corresponding vegetation and evolution process under different intensity roots are given numerical simulations. results show that as increases, isolation degree increases indicates robustness ecosystem decreases. Besides, reveal diffusion coefficient change structure is: stripe pattern$ \rightarrow $mixed $spot pattern. Our effects on distribution, provide theoretical basis for study vegetation.

Global warming is increasing the frequency and intensity of heat waves droughts. One important phase in life cycle plants seed germination. To date, association temperature water potential thresholds germination with traits has not been explored much detail. Therefore, we set up different gradients (5–35 °C), (−1.2–0 MPa), × combinations for nine native Loess Plateau region to clarify suitable their Meanwhile, elucidated correlations mean mass flatness index by using thermal time hydrotime models. According our findings, rate was positively correlated percentage potential, former rising latter decreasing as increased. Using models, could be predicted accurately, studied species varied an increase percentage. Moreover, altered impact on rate. Overall, base germination, but threshold, negatively lower rounder seeds than longer seeds. This study contributes improving understanding characteristics typical implications management vegetation restoration degraded grasslands.

Managing uncertainties and risks is always a difficult but fascinating task in fresh fruit supply chains, especially when dealing with the strategy for production conveyance of Vietnam. Following COVID-19 outbreak, confluence economic recession persistent adverse weather conditions has exacerbated challenges faced by dragon cultivators. This research investigates two-stage stochastic programming (TSSP) approach which developed served as valuable tool analyzing uncertainties, optimizing operations, managing industry, ultimately contributing to sustainability resilience chains agricultural sector. A prototype provided illustrate complex dynamic nature cultivation consumption Data on selling prices were collected from several sources between 2013 2022 Binh Thuan Province, The results obtained model using three different approaches order their versatility efficacy: (1) Scenario tree generation; (2) Sample average approximation; (3) Chance-constrained programming.
