Excessive agricultural investment brought about by increased multiple-cropping index may compromise environmental sustainability. There are few studies on the sustainability of diversified multi-cropping systems in Yangtze River Basin (YRB). Therefore, this study selected five representative locations YRB. According to local climate characteristics and food demand, were designed, main winter crops as previous corn-soybean strip compound cropping system, with traditional double-cropping model control (CK). The emergy evaluation method was introduced quantitatively compare efficiency results showed that incorporating soybean intercropping corn, compared CK, total energy input, annual output, economic output 15.80%, 9.78%, 33.12% average, respectively. unit value (UEV) non-renewable (UNV) 6.03% 5.98%, respectively; yield ratio (EYR) loading (ELR) decreased 0.91% 0.44%, (ESI) same. In third mature crop selection, ELR 14.32%, ESI 18.55%. addition, choice plays a vital role system's Compared those other crops, outputs potato (upper reaches YRB), or forage rape (middle wheat (lower YRB) 51.02%, 32.27%, 0.94%, their 71.21%, 47.72%, 12.07%, Potato-corn/soybean potato/corn/soybean rape-corn/soybean wheat-corn/soybean chosen facilitate coexistence high benefits Additionally, promoting mechanization reducing labor input essential improve systems. This would provide scientific basis theoretical support for development efficient sustainable dryland

Ecosystem services (ES) such as carbon storage (CS), soil conservation (SC), habitat quality (HQ), and water yield (WY) play a crucial role in maintaining ecological balance supporting sustainable regional development. With increasing environmental changes, understanding the spatiotemporal dynamics of these their driving factors has become essential science. This study focuses on Nanchang metropolitan area, quantifying CS, SC, HQ, WY from 2000 to 2020. It explores impacts major factors, including climate, topography, social aspects, spatial heterogeneity ES. The results reveal that between 2020, CS HQ decreased by 0.1385×108 tons/ha 0.0507, respectively, while SC increased 2.4754×10 9 1.6668×10 10 m 3 , respectively. Notable exists correlation changes distribution ESs is higher mountainous regions compared central plains. Among human population (POP) gross domestic product (GDP) predominantly influenced whereas climate POP drove SC. Changes were primarily affected topography. These findings suggest need focus key formulate targeted land policies aimed at enhancing ES value area.
