江西富硒农业产业发展问题与对策研究基于江西省宜春市的调查

江西省拥有丰富的硒资源,富硒农业已成为江西绿色生态农产品品牌的又一张名片。江西省宜春市富硒土壤面积居全省第一,富硒农产品种类多、涵盖面较广,富硒农业走在全省前列。本课题组通过对江西省宜春市富硒农业产业发展的实地调研、与行业企业和政府部门人士访谈,在总结宜春市富硒农业发展的成功经验基础上,发现宜春市富硒农业存在“富硒资源本底不清、少量地块硒与重金属伴生现象不明、科研支撑能力不强、富硒农产品标准不全、产业规模体量不大、产业链上企业带动不强”等问题。基于宜春市富硒农业产业发展经验提出了江西富硒农业高质量发展的六项政策建议：建立重点富硒区域（重点基地）、支持重点富硒产业、扶持重点富硒企业、攻克重点富硒技术、树立重点富硒品牌、优化重点富硒产业政策。通过以上政策措施来助跑江西省特色农业发展,提升江西富硒农业产业的知名度和市场竞争力。     

基于农户生计策略选择影响因素的生计资本度量——以四川省402户农户为例简

为探索农户生计资本的客观定量评价,以2012年在四川省抽样调查的402户农户数据为基础,借鉴英国国际发展机构(DFID)的可持续生计分析框架,将5类生计资本下的12个二级指标对农户生计策略的3个水平——纯农型、兼业型、非农型进行无序多分类Logistic回归,选择出显著的变量及其偏回归系数,用该系数构造生计资本大小的评价权重,对生计资本进行客观定量评价.结果发现:对农户生计策略选择影响显著的变量有现金收入、耕地面积、赠送礼金等6个变量;在农户生计资本评价中,现金收入占其权重的64.4%,前3个重要变量——现金收入、耕地面积、赠送礼金权重占比达89.2%;大多数农户选择兼业型的生计策略,选择不同生计策略的农户生计资本水平差异较大,稳定水平也不同.?更多还原     

Coupling Relationship between Transport Superiority Degree and Urbanization in Sichuan,China

Relationship between transport superiority degree and urbanization is not quantified enough in recent researches.Combined with coupling model and coupling coordination model,the spatial analysis technique was applied to quantitatively analyzing the relationship between transport superiority degree and comprehensive urbanization in eighteen prefecture-level cities in Sichuan from 2000 to 2011. An evaluation index system was constructed,and index weights were obtained using the variation coefficient method. The traffic volume was found to be the main factor contributing to transport superiority degree, and space urbanization was the primary factor influencing comprehensive urbanization. The coupling degree between transport superiority degree and urbanization（ CU） was generally higher than the coupling coordination degree（ DU） in 2000-2011. DUvaried more significantly than CU. In 2011, Sichuan was divided into five regional types. Based on the above observations, targeted recommendations were developed.
