黄河デルタの塩性アルカリ農地で3年間の圃場試験を行い、トウモロコシ単作と比較して、トウモロコシ-大豆間作とトウモロコシ-ピーナッツ間作の生産性、経済性、炭素フットプリント（CF）、炭素持続可能性指標（CSI）を評価した。間作は経済収量をやや減らすものの、換算収量と純収入を増加させ、CFを削減しCSIを向上させた。総合評価ではトウモロコシ-ピーナッツ間作が最適で、塩性アルカリ地域の環境に優しい栽培様式として有望である。
English
A three-year field experiment in the Yellow River Delta's saline-alkali farmland compared maize monoculture with maize-soybean and maize-peanut intercropping. Intercropping slightly reduced economic yield but increased maize-equivalent yield and net income, while reducing carbon footprint and improving carbon sustainability index. Maize-peanut intercropping showed the best overall performance, offering a promising eco-friendly planting pattern for saline-alkali regions.

📄 Abstract（原文）
To alleviate the constraints of coastal saline-alkali soil on crop production and explore efficient and low-carbon planting patterns for vulnerable saline land ecosystems, a three-year continuous field experiment was carried out in the coastal saline-alkali farmland of the Yellow River Delta, Dongying City, Shandong Province, China. Using sole maize cropping (CM) as the control, this study systematically compared productivity, energy budget, economic benefit, carbon footprint (CF), and the carbon sustainability index (CSI) of maize–soybean intercropping (M/S) and maize–peanut intercropping (M/P), and further evaluated their comprehensive benefits based on the net ecosystem economic benefit (NEEB). The results showed that compared with CM, the three-year average economic yield of M/S and M/P decreased by 14.6% and 14.0%, with corresponding energy yield reductions of 12.0% and 9.1%. Notably, M/S and M/P significantly increased the maize equivalent yield by 9.4%. Relative to CM, the three-year average net income of M/S and M/P increased by 18.3% and 29.9%, respectively. For carbon-related environmental benefits, M/S and M/P reduced CF per unit maize equivalent yield by 14.0% and 18.1% and CF per unit economic benefit by 13.9% and 18.0%, while increasing the CSI by 6.0% and 8.4%, respectively. Comprehensive evaluation using the Z-score method demonstrated that M/P improved the NEEB by 9.4% and obtained a higher comprehensive score than CM, while M/S produced a marginally lower Z-score than CM. Overall, M/P exhibited the optimal multi-dimensional performance and represents a promising eco-friendly planting pattern for coastal saline-alkali regions.
