中文摘要:基于DPSIR概念模型,构建中尺度水土流失综合治理生态环境效应评价指标体系,对退耕还林(草)实施的生态环境效应进行评估。结果表明:生态恢复环境效应综合值在退耕还林(草)试验、实施和恢复阶段分别较评价初期增加了30%、43%和56%;环境分项值则减小了6%、20%和22%,社会分项值增加了43%、114%和143%;经济分项值增加了29%、129%和129%。退耕还林(草)、耕地压力、输沙模数和侵蚀性降水量等驱动和压力因子是生态恢复环境响应的敏感指标,退耕还林(草)对生态环境的作用需要一定的时期才能被生态环境所响应。

Abstract:An index system was constructed for accessing eco-environmental effect of water and soil loss comprehensive harness in meso-scale based on the DPSIR model. The eco-environmental effect of grain for green project was accessed. The results showed that comprehensive value of environmental effect of ecological restoration increased by 30% in test stage, 43% in formal implement stage, 56% in restoration stage, respectively compared with those in the initial stage of evaluation; whereas the values of environmental subentry decreased by 6%, 20% and 22%, respectively; values of social subentry increased by 43%, 114% and 143%, respectively; the values of economic subentry increased by 29%, 129% and 129%, respectively. Grain for green, farmland pressure, sediment transport modulus and erosive precipitation were sensitive indices which indicated that there was a hysteretic nature of eco-environmental changes compared with driving and pressure factors. Impacts of the project of grain for green for eco-environment to response usually need a period of time.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
