Construction of eco-quality dual-suitable distribution areas for <i>Dictamnus dasycarpus</i> Turcz.: integrated analysis of MaxEnt model and multidimensional indicators.

ABSTRACT:

Introduction

Dictamnus dasycarpus Turcz., a critical traditional medicinal plant in Northeast China, faces challenges of habitat degradation and unstable quality in cultivated populations.

Methods

This study systematically analyzed the key environmental drivers of its distribution and quality formation in Liaoning Province through an integrative framework combining the Maximum Entropy model (MaxEnt), High-Performance Liquid Chromatography (HPLC), and geodetector analysis.

Results

July precipitation (Prec7), temperature seasonality (Bio4), May solar radiation (Srad5), March maximum temperature (Tmax3), and March minimum temperature (Tmin3) were core variables influencing distribution patterns. The quality of cultivated populations was primarily regulated by Febr
