| 以上海市70条代表性道路的行道树为研究对象，开
展行道树健康评价，并分析土壤理化性质与行道树健康的相关
性。结果表明：大多数行道树处于基本健康状态，20%存在
较严重的健康问题；土壤物理性质与行道树健康密切相关，其
中行道树健康与土壤容重、砂粒含量极显著负相关，与土壤含
水量、总孔隙度、黏粒、粉粒含量等极显著正相关；多数化学
性质与行道树健康状况无显著相关性。研究结果可为城市行道
树土壤的改良和精心化管理提供参考。 |

| Correlation between Soil Physical and Chemical Properties and Street Trees Health in Shanghai |

| Abstract: |
| Taking the street trees of 70 representative roads in
Shanghai as the research object, the health evaluation system of
street trees was constructed and the correlation between soil physical
and chemical properties and street tree health were analyzed. The
results show that: most street trees in Shanghai are in the healthy
state, and 20% street trees are in the weak state. Soil physical
properties are closely related to the health status of street trees, which
has a very significant negative correlation with soil bulk density
and sand content, and has a very significant positive correlation
with soil water content, total porosity, clay and silt contents. Most
chemical properties have no significant correlation with the health
status of street trees. The research results can provide reference for
the improvement of urban street tree greening soil and the careful
management of urban green space. |
