摘要
以陕北延安市城郊赵庄村为研究对象,以农户地块调查和土壤类型相结合,选取了高、中、低收入农户共33户进行了实地调查,其中涉及到298块地块和14种土地利用方式,28种分析单元。在C—D生产函数模型分析基础上,将地块尺度和流域尺度结合起来进行城郊农村土地生态经济适宜性分析,探索生态效益和经济效益的融合点。研究结果表明,除部分红土类型外,延安市赵庄村大多数土地的生态类型对于农业基本是适宜的。但是除部分对于比较传统的种植业高度适宜外,其他都基本适宜,适宜度并不很高。对于传统的种植作物,如玉米、谷糜,在以后的管理中,要提高经济效益,需要多施有机肥,做到合理施肥。对于小瓜、大棚蔬菜等特色种植业,应以提高技术水平为主,提高其经济效益。对于豆类、白菜种植来说,劳动力对其产量影响程度很小;对于薯类和萝卜,技术水平对其影响可以忽略。
This research was conducted to investigate land use patterns and soil types in Zhaozhuang, a village of Yanran City in Northern Shaanxi Province. 298 land parcels, 14 land utilization patterns and28 analysis units were analyzed according to 33 high, medium and low-income household surveys. Based on the Cobb-Douglas production function model, the plot scale and the watershed scale were combined to analyze the eco-economic suitability of suburban rural land and explore the integration of ecological and economic benefits. Results showed that most of the land ecosystem types in Zhaozhuang village are appropriate for agriculture, except part of the laterite type. However, only some are highly suitable for traditional farming, while the othersr suitability is not so high. For traditional farming such as corn and cereal, more organic fertilizers and rational fertilization are needed for an improved economic efficiency. For featured farming such as small melons and greenhouse vegetables, improving the technical level is more important. For beans and cabbage farming, labor is less important for their yields. For tuber crops and turnips, the effects of technical level can be ignored.
