| 中文摘要: |
| 我国土壤地球化学调查资料丰富，但其科技成果转化水平还有待进一步提高。为了提高杭州市余杭区土地质量地球化学调查成果的科技转化潜力，本研究针对余杭区名优茶叶，综合运用层次分析法及模糊数学评判法，建立了区域土壤种植区划适生模型，并结合地理信息系统，提出了种植区划建议。结果表明：茶多酚、游离氨基酸以及水浸出物是影响茶叶品质的主要营养成分；土壤类型、海拔高度、土壤pH和坡度是影响茶叶适生的主要宏观因子，而N、P、K以及微量元素Zn是影响茶叶品质的主要微观影响因子。基于此，将余杭区茶叶品质分为优、良及一般三类，并建立了余杭区茶叶土壤适生模型。利用适生模型，将余杭区茶叶种植区域划分为四个类型：高度适宜区、中度适宜区、低度适宜区以及不适宜区。研究表明，余杭区百丈镇和鸬鸟镇是提高余杭区茶叶产量的重点区域，建议适宜扩大该区域径山茶叶种植面积。 |

| Although soil geochemical survey data are abundant in China, the transformation level of its scientific and technological achievements needs to be further improved. To improve the potential of scientific and technological transformation of geochemical survey results of land quality in Yuhang District, Hangzhou, Zhejiang, a suitable model of regional soil planting regionalization of the famous and excellent quality tea in Yuhang District was established using an analytic hierarchy process and a fuzzy mathematical judgment method. Combined with GIS, suggestions for planting regionalization were put forward. The results showed that:tea polyphenols, free amino acids, and water extracts were the main nutrients affecting tea quality; soil type, altitude, soil pH, and slope were the main macroscopic factors affecting the fitness of tea, while N, P, K, and trace elements such as Zn were the main microscopic factors. Based on this, three types of tea quality were established:excellent, good, and genera. In addition, a suitable model of tea soil in Yuhang District was also established. Using the fitness model, the tea planting area in Yuhang District was divided into four types:a highly suitable area, a moderately suitable area, a lowly suitable area, and an unsuitable area. The results showed that the Baizhang and Luniao towns in Yuhang District were key areas for increasing tea production in Yuhang District. It is recommended that the area of Jingshan tea planting in this region should be expanded. |
