The impact of climate change on medicinal plants has significantly altered their suitable environments, thereby affecting the quality herbal medicines. Notopterygium franchetii (N. franchetii), a plant intricately linked to its natural habitat, exhibits substantial variations influenced by ecological conditions native region. In this study, comprehensive field surveys were conducted gather occurrence records and samples N. franchetii. Maxent model ArcGIS software employed predict habitats during different time periods. A high-performance liquid chromatography (HPLC) method was developed establish chemical fingerprints 21 sample batches. Fourteen common peaks subjected cluster analysis, principal component orthogonal partial least squares-discriminant analysis. findings revealed correlated with geographic origins, identifying 10, 1, 14, 3, 4 as crucial for differentiation. study indicates that precipitation, temperature, altitude influence distribution Under current conditions, habitat area is estimated be approximately 94,637.33 km2. However, projections under three future scenarios suggest declining trend in areas. zoning map developed, integrating correlation between composition environmental variables spatial analysis visualization capabilities ArcGIS. high-quality regions are predominantly located Gannan, Linxia, Dingxi, Longnan, Wuwei districts. These research outcomes offer valuable reference cultivation areas assessing Gansu Province.

Assessing Rice Sheath Blight Disease Habitat Suitability at a Regional Scale through Multisource Data Analysis

Remote Sensing, Journal Year: 2023, Volume and Issue: 15(23), P. 5530 - 5530

Published: Nov. 28, 2023

Extensive occurrence of rice sheath blight has been observed in China recent years due to agricultural practices and climatic conditions, posing a serious threat production. Assessing habitat suitability for at regional scale can provide important information disease forecasting. In this context, the present study aims propose regional-scale evaluation method Yangzhou city using multisource data, including remote sensing meteorological survey data. By combining epidemiological characteristics crop Relief-F algorithm, some variables from key stages were selected. The maximum entropy (Maxent) logistic regression models adopted compared constructing assessment model. results algorithm showed that specific temporal phases are particularly crucial evaluating suitability, MODIS products LAI (4–20 August), FPAR (9–25 June), NDVI (12–20 LST (11–27 July). Based on these features, Maxent model yielded better accuracy than model, with an area under curve (AUC) value 0.90, overall (OA) 0.75, true skill statistics (TSS) 0.76. Indeed, consistent actual distribution area, suggesting promising predictive capability. Therefore, it is feasible utilize remotely sensed assessing scale. proposed expected facilitate prevention control disease.

Abstract Gymnosia orchidis ( G. ) is a valuable Tibetan medicinal resource with significant medicinal, ecological, and economic value. However, the growth of severely constrained by stringent natural conditions, leading to drastic decline in its resources. Therefore, it crucial study suitable habitat areas facilitate future artificial cultivation maintain ecological balance. In this study, we investigated zones based on 79 occurrence points Qinghai-Tibet Plateau (QTP) 23 major environmental variables, including climate, topography, soil type. We employed Maximum Entropy model (MaxEnt) simulate predict spatial distribution configuration changes during different time periods, last inter-glacial (LIG), glacial (LGM), Mid-Holocene (MH), present, scenarios (2041—2060 2061—2080) under three climate (SSP126, SSP370, SSP585). Our results indicated that annual precipitation (Bio12, 613—2466 mm) mean temperature coldest quarter (Bio11, -5.8—8.5 °C) were primary factors influencing , cumulative contribution 78.5%. The driest season had most overall impact. Under current covered approximately 63.72×10 4 /km², encompassing Yunnan, Gansu, Sichuan, parts Xizang provinces, highest suitability observed Hengduan, Yunlin, Himalayan mountain regions. past, area experienced Mid-Holocene, variations total centroid migration direction. scenarios, projected expand significantly SSP370 (30.33%—46.19%), followed SSP585 (1.41%—22.3%), while contraction expected SSP126. Moreover, centroids exhibited multidirectional movement, extensive displacement (100.38 km²). This research provides insights for guiding selection introduced species, cultivation, conservation future, also offering theoretical support protection endangered species.
