不同生计类型农户的土地利用——三峡库区典型村的实证研究 总被引：14，自引：0，他引：14
采用分层随机抽样、参与式农村评估、地块调查等方法,研究了重庆市涪陵区珍溪镇3 个典型村样本农户的土地利用和土地投入的差异。共调查了227 户,2250 个地块。结果发现：① 除了6.17%的非农户土地撂荒、退耕或出租外,纯农户、一兼户、二兼户的土地利用类型均以集约为主。纯农户因年龄结构老龄化,劳动力供应不足,相对粗放的耕地面积为48.95%。一兼户相对集约利用的面积比例为71.08%。二兼户相对集约利用的面积比例为67.20%。② 土地投入有明显差异。纯农户每公顷农业劳动力投入少,劳动力老龄化;由于缺乏资金,农业机械及省工性投入少,多选择农家肥及磷肥、碳铵等价格较低的传统肥料。一兼户劳动力投入的数量与质量都最高,有长期投资农业的意愿与动力,农业机械投资量最大,保持了较高的农家肥施用量,且各种化肥配合施用,用量适中;二兼户每公顷农业劳动力投入大,以老人与妇女为主;由于收入高,农业机械及省工性投入比纯农户多,首选价格高、省劳力的化肥。非农户无土地投入。` 相似文献

新型城镇化建设鼓励农村剩余劳动力向城市转移,同时农村劳动力转移的持续发展又进一步加大了对新型城镇化建设的支持力度.由于劳动者的整体素质较低以及务工领域低端化等因素的存在,农村劳动力转移具有一定的脆弱性.甘肃省城镇化水平滞后、城乡差距较大等问题依然突出,农户作为农村地区最主要的经济活动主体与最基本的决策单位,劳动力转移的状况直接影响到其生计水平和区域生态安全.以甘肃省14个地州市为研究区,通过对可持续生计框架的应用,揭示劳动力转移的关键性因素,定量评估劳动力转移对农户生计资本的影响程度,总结出有利于提高甘肃省农户发展能力、改善农户生计水平的政策建议,从而为促进西部地区可持续发展、缓解贫困、实现精准扶贫提供参考依据. 相似文献

依据英国国际发展署(DFID)提出的可持续生计分析框架为指导,选取与农户生计资产密切相关的评价因子,建立农户生计资本评价指标体系,对云南省25个沿边县域中具有不同地形特征的64个村寨生计资本进行了测算、对比和分析。研究发现,研究区生计资本总体水平偏低,不同地形特征下村寨间生计资本差异性较大,生计资本不平衡,针对不同的生计脆弱性,提出如下讨论:(1)人力资本上,着重加强和巩固教育和培训力度;(2)金融资本、社会资本上,加大农业现代化水平的投资力度,加大加强农业合作组织的建设;(3)物质资本上,建议增加对农业基础设施和信息媒体的建设;(4)在自然资本的脆弱性上,要在可持续性利用的基础上,大力发展循环经济。 相似文献

在实地调查和深入访谈的基础上,对泸沽湖机场建设移民搬迁后移民的生计转变、文化调适和社会整合等进行了阐述和分析。研究表明,从高寒山区下移安置到现居地后,移民原有的生计模式、经济结构、饮食习俗和居住格局纷纷被打破重构,同时还面临家支血缘关系网络解体、宗教信仰和观念淡化以及精神文化缺失等社会和心理方面的冲击与挑战。相关研究应加强对移民文化变迁、社会适应和心理认同的关注,从人本出发促进移民地区的文化融合与和谐发展。 相似文献

帮扶措施不仅是构建稳定脱贫长效机制的关键举措,更是推进脱贫攻坚与乡村振兴有效衔接的客观要求。论文构建了帮扶措施对农户生计策略选择的影响分析框架,利用入户调查数据,在辨明帮扶措施及生计策略选择特征的基础上,探讨了影响陇南山区脱贫户生计策略选择的关键因素。结果表明：(1)陇南山区有59.84%的脱贫户享受了多元帮扶措施,其中,享受最多的多元帮扶措施为产业扶贫+生态补偿扶贫,享受最多的单一帮扶措施为生态补偿扶贫;(2)陇南山区脱贫户的生计策略以务工主导型为主,呈农业特色化、非农化和多样化的特点;(3)陇南山区脱贫户生计策略选择的路径依赖性整体呈中等水平,其中,川坝河谷区农户、老年农户和低生计资本禀赋的农户生计策略选择的路径依赖性较强,且帮扶措施对其有调节作用;(4)社会资本、人力资本、金融资本和区位条件对农户的生计策略选择有显著影响;产业扶贫和电商扶贫对农户的特色务农型生计策略选择有正向影响,生态补偿扶贫和就业扶贫对农户的非农化生计策略选择有正向影响。最后,提出了优化农户生计策略的政策建议。 相似文献

As the foundation of farm household structure, livelihood asset status is the basis for farmers to gain opportunities, adopt livelihood strategies, resist livelihood risk, and engage in positive livelihood achievements. Quantifying farm household assets identifies future development trends that are fundamentally necessary to predict farm household vulnerability and strategy, as well as understanding farmers’ current living situations. Using Zunyi City in China’s western mountainous area as a case study, we conducted stratified sampling and participatory rural investigation appraisal to collect data on the attributes of farm households’ livelihood assets and livelihood strategies to establish an index evaluation system and enable evaluation and analysis of farm households with different livelihood strategies. Our research indicates that due to structural differences, total livelihood assets of farm households with different livelihood strategies are similar. Rural households have an abundance of natural and material assets and deficiencies in human, financial and social assets. Non-rural households and part- time households are abundant in human, financial and social assets and deficient in natural and material assets. 相似文献

Based on objective data collected from interviews in typical villages of the Three Gorges Reservoir Area, the present study devised three livelihood scenarios related to rural transformation development: agriculturally dominant livelihood, multiple-type livelihood and non-agriculturally dominant livelihood. Moreover, the present study reports the trend characteristics of nonpoint source pollution load of crop farming in relation to the transformation of dominant livelihood types, and discussed the primary factors which affect livelihood type transformations. Results indicated the following: (1) The current farmland pattern shows a trend of diversification as self-cultivation, cropland transfer and fallow in the sample region. Dynamic characteristics of cultivated land present a special feature that is more “transfer-into” than “transfer-out”. Various scales of planting are represented among the various households, according to the following decreasing order: half-labor household > non-labor household > adequate labor household. (2) The highest pollution loading produced by crop farming occurs in half-labor households while the lowest occurs in non-labor households. With increasing labor, the pollution load per unit area tends to first increase and then decrease within families with enough labor. (3) As the type of livelihood transitions from agriculturally dominant to non-agriculturally dominant, the maximum reduction of total pollution loading produced by the agricultural industry can reach 72.01%. Compared to agriculturally dominant livelihoods, multiple-type livelihoods produce a pollution load reduction yield of 19.61%–29.85%, and non-agriculturally dominant livelihoods reduce the pollution load yield by 35.20%–72.01%. However, the rate of reduction of total nitrogen is not the same as total phosphorus. (4) The non-agricultural characteristics of labor allocation and income promote the transformation from dominant livelihood types to non-agricultural livelihoods, while potential revenue conversion follows a similar trend. In addition, different household types do not display identical conversion rates, according to the following decreasing order: enough labor household > half-labor household > non-labor household. (5) During rapid urbanization and the building of new industrial systems, the livelihood types of rural households have been further transformed to off-farm household types in the mountainous region; this process will lead to the further reduction of pollution load generated by planting and agriculture. Hence, significant decreases in the planting pollution load necessitate the development of control measures to enhance transformations from agricultural to off-farm livelihoods. 相似文献

基于旅游公平理论,从政府民生活动对当地居民的影响角度提出了"旅游民生感"概念和实际民生感、期望民生感、比较民生感3个测量维度,通过问卷调研数据和对应分析方法进行了实证研究。结果发现:民族地区居民年龄越大对其实际民生感越满意,而工人和中等学历居民则倾向于不满意;对于期望民生感,学生、工人、中低收入和距离景区近的人群趋于不满意;农民的比较民生感趋于满意,而企事业人员、中低收入者、居住地与景区距离居中的人群和高学历人群则对比较民生感趋于不满意。最后,从统筹兼顾、社区公平和弱势群体改善民生诉求3个方面提出了政策建议。 相似文献
