【摘要】 基于湖北监利县、公安县、潜江市、洪湖市、石首市5个县(市)的实地调研数据，构建能量流动模型，并运用能值分析方法，计算5个县(市)稻虾综合种养系统的能值投入产出情况以及相关指标，揭示稻虾综合种养系统环境影响的空间差异。结果表明，从整体上看，5个县(市)的稻虾综合种养活动尚未对环境造成显著压力，显示出良好的生态效益。但内部存在明显的空间差异，东南部地区如监利、洪湖等依赖自然资源较多，可持续发展指数较高；西北部地区如潜江等则呈现出高投入高产出的特点，环境负载率相对较高。更多还原

【Abstract】 Based on field research data from five counties(cities) in Hubei Province, including Jianli County, Gong’an County, Qianjiang City, Honghu City and Shishou City, an energy flow model was constructed.Using energy analysis methods, the energy input-output situation and related indicators of the rice-crayfish rotation system in the five counties(cities) were calculated, revealing the spatial differences in the environmental effect of the rice-crayfish rotation system.The results showed that overall, the rice-crayfish rotation system in the five counties(cities) had not caused significant pressure on the environment, demonstrating good ecological benefits.However, there were obvious spatial differences within the region.Southeast regions such as Jianli and Honghu relied more on natural resources and had a higher sustainable development index; Northwest regions such as Qianjiang exhibited high input and output, with relatively high environmental load rates.更多还原
