摘要: 可持续农业与农村发展(SARD)是发达国家与发展中国家面临的共同问题,而不同地区SARD所处的阶段不同,发展模式也各具特色。科学地确定其发展偏离度并为其未来发展作出合理的规划,具有重要的理论与实践意义。文章构建了SARD多目标规划模型,运用它对常熟市过去8年进行了系统评价,并对未来发展进行了动态规划,得出了3个不同的投入方案。

Abstract: Both developed and developing countries face to sustainable agriculture and rural development(SARD).The stage of SARD in different areas is different, and their developing pattern is various.It is meaningful both in theories and practices to scientifically appraise the deviation of SARD and to reasonably draw up plans for regional development.In this paper, based on the designed appraisal thinking, a multi objective planning model is designed, which is
(Vp) Fmax =(f1,f2,...,fm)
s.t.∑ =1Xlt≤cl, l=1,2,...,s
Xlt ≥0,t=1,2,...,nl,
We do our researches by taking Changshu City as an example.Firstly, we establish an indicator system of Changshu SARD, which includes 28 input and 30 output indicators.In establishing the indicator system, we act upon the basic thoughts of SARD that sustainable agriculture and rural development is synthetic outputs of various inputs containing resources, environment, manpower and economic factors.That is to say, not only direct economic inputs, but the use of resources and the burden of environment are regarded as input factors; meanwhile, the outputs not only contain economic and social factors, but contain the factors of environmental quality.And based on the framework of this indicator system, we establish a database of sustainable agriculture and rural development of Changshu(CSSARD) and an auxiliary database(ACSSARD), and standardize them through efficacy function.Then using the model mentioned above, we appraise the results of sustainable agriculture and rural development in Changshu from 1990 to 1997.It is shown that the degree of the developing deviation to the best possibility in the 8 years is respectively 0.25, 0.28, 0.10, 0.17, 0.12, 0.08, 0.17, 0.19.That is to say, the developing situation in 1995 is the most satisfied, while that in 1991 is the most unsatisfied.In the end of the paper, through dynamic simulation on computer, we get three different input plans:(1) laying emphasis on technology and economics, which stresses high benefits";(2) laying emphasis on operation of manpower resources, which stresses intensification"; and(3) synthetic balancing plan, which is designed by comprehensively adhering to the connotation of model of high benefits, intensification and sustainability.As an example, the concrete planning data in 2000 is given in the paper.
