基于 Logistic-ISM 模型的喀斯特地区农户石漠化治理行为影响因素及调控研究
喀斯特地区农户的石漠化治理行为对保障我国长江、珠江流域生态安全极为重要。为了深入了解农户石漠化治理行为的影响因素,促进石漠化治理政策的落实和治理工作的有效开发,本文选取了贵州省3个典型的石漠化县,晴隆县、关岭县、黔西县为研究区,应用参与性农户评估法对437位农户开展治理行为调查。以调查数据为基础,结合运用 Logistic 回归模型与 ISM 分析方法研究农户石漠化治理行为的主要影响因素及其层次结构,实现对石漠化治理行为的剖析。分析结果显示:距最近乡集镇距离、是否自愿选择技术、接触信息次数、交流信息次数是表层直接影响因素,石漠化面积是中层间接因素,家庭农业收入、是否有科研治理项目、专家走访次数...

Summary: | 喀斯特地区农户的石漠化治理行为对保障我国长江、珠江流域生态安全极为重要。为了深入了解农户石漠化治理行为的影响因素,促进石漠化治理政策的落实和治理工作的有效开发,本文选取了贵州省3个典型的石漠化县,晴隆县、关岭县、黔西县为研究区,应用参与性农户评估法对437位农户开展治理行为调查。以调查数据为基础,结合运用 Logistic 回归模型与 ISM 分析方法研究农户石漠化治理行为的主要影响因素及其层次结构,实现对石漠化治理行为的剖析。分析结果显示:距最近乡集镇距离、是否自愿选择技术、接触信息次数、交流信息次数是表层直接影响因素,石漠化面积是中层间接因素,家庭农业收入、是否有科研治理项目、专家走访次数是深层根源因素。因此,农户农业收入低、资金投入匮乏和石漠化治理相关技术缺乏是导致农户石漠化治理积极性不够的根本原因。建议多渠道增加农民收入,以推动农户参与石漠化治理的积极性;改善农村基础设施条件以降低石漠化治理的成本;完善石漠化治理技术推广体系,提高农户石漠化治理技能。 |

Agronmy College, Anshun University, Anshun, Guizhou 561000, China) Restoration of rocky desertification by households in karst areas is vital for the ecological security of the Yangtze River and Pearl River Basins.In order to understand the factors affecting household behavior to control rocky desertification,and promote implementation and management in effective prevention of rocky desertification,three typical counties with rocky desertification conditions were selected for the case study:Qinglong,Guanling,and Qianxi.The behavior of 437 households with respect to control of rocky de-sertification was investigated using the participatory rural appraisal method.Based on the survey data,Lo-gistic regression analysis and the ISM method were used to determine factors affecting household behavior to control rocky desertification and their hierarchy structure.The results indicate that the dist |
