Abstract

Based on the maximum entropy modeling (Maxent) and ArcGIS tool, this study assessed the potential of marginal land and analyzed the impact of environmental variables for Jerusalem artichoke (Helianthus tuberosus L.) in Shaanxi Province, China. The results showed that the dominant land type used for the growth of Jerusalem artichoke was moderately dense grassland. Additionally, significant environmental variables of Jerusalem artichoke and their suitable range in Shaanxi Province were average slope (SLP, 0–5°C), average soil depth (DPT, 1.50–1.60 m), max temperature of the warmest month (Bio5, 30–31°C), annual mean temperature (Bio1, 16.5–18.0°C), precipitation of the wettest quarter (Bio16, 0.01–0.02 m), July solar radiation (SR7, 1.66–1.67 × 107 W/m2), precipitation seasonality (Bio15, 50–60%), precipitation of the driest quarter (Bio17, 0–0.005 m), and isothermality (Bio3, 265–275). Furthermore, the suitable area was mainly distributed in southern (mainly Hanzhong, Ankang, and Shangluo) and northern (mainly Yan’an and Yulin) parts of Shaanxi Province, covering around 8.81 × 1010 m2 and accounting for 42.8% of the total area of the Shaanxi Province. This study can provide a reference for the rational planting of Jerusalem artichoke in Shaanxi Province.

Highlights

Climate change has garnered huge attention worldwide, and rising greenhouse gas emissions are the primary drivers of climate change (Jhariya et al, 2019; Jhariya et al, 2021a; Jhariya et al, 2021c)
The main objectives of this study are as follows: 1) to determine the distribution of Jerusalem artichoke in Shaanxi Province; 2) to identify the most critical environmental variables for Jerusalem artichoke and determine their effects on the spread of Jerusalem artichoke; and 3) to access the potential marginal land resources suitable for planting Jerusalem artichoke in Shaanxi Province, and the habitat suitability of Jerusalem artichoke
2.4.6 Results Processing By superimposing Shaanxi Province marginal land data on the Maxent result, the distribution of marginal land suitable for Jerusalem artichoke was eventually produced

Summary

Introduction

Climate change has garnered huge attention worldwide, and rising greenhouse gas emissions are the primary drivers of climate change (such as carbon dioxide and methane) (Jhariya et al, 2019; Jhariya et al, 2021a; Jhariya et al, 2021c). The massive usage of fossil fuels has led to a rapid increase in greenhouse gas emissions (Foster, 2019; Jhariya et al, 2019). The United Nations Framework Convention on Climate Change (UNFCCC) was conducted to control carbon dioxide and other greenhouse gas emissions (Jhariya et al, 2019). Replacing or reducing the usage of fossil fuels with renewable energy is an effective way to reduce carbon emission (Maddalwar et al, 2021; Zhang B. et al, 2021). As one of the largest consumers of fossil energy and carbon emitter globally (Mi et al, 2017; Shi et al, 2022), the Chinese government actively responded to international carbon neutral actions (Nie et al, 2022), and it urgently needs to explore economical and environmentally friendly renewable energy sources to achieve carbon emission reduction targets.
