【摘要】：基于2010年遵义市土地利用和社会经济数据,对遵义市生态系统服务价值与土地生态安全协调度进行分析。结果表明:全市土地生态安全水平西南低,东北和西北高;平均生态系统服务价值呈现西南部低,其他地区高。生态系统服务价值与土地生态安全协调度类型以严重失调和良好协调为主,西南部以严重失调和中度失调为主,其他地区以良好协调为主;生态系统服务价值与土地生态安全协调发展类型以中等协调发展和协调发展类型为主,西南部以严重失调衰退和中度失调衰退为主,中东部以中等协调发展为主,北部和西部以协调发展类型为主。社会经济水平和生态系统空间格局的异质性是导致遵义市各地区生态系统服务价值与土地生态安全协调度存在差异的重要因素。
[Abstract]:Based on the data of land use and social economy in Zunyi City in 2010, the coordination degree between ecosystem service value and land ecological security in Zunyi City was analyzed. The results showed that the level of land ecological security was low in southwest and high in northeast and northwest, and the average ecosystem service value was lower in southwest and higher in other areas. The main types of coordination degree between ecosystem service value and land ecological security are serious imbalance and good coordination, the southwest is mainly serious and moderate imbalance, and other areas are mainly good coordination. The main types of coordinated development between ecosystem service value and land ecological security are moderate coordinated development and coordinated development, while the southwest is dominated by serious maladjustment and moderate maladjustment, and the central and eastern regions mainly by moderate coordinated development. The northern and western regions are dominated by coordinated development. The heterogeneity of social economic level and ecosystem spatial pattern is an important factor leading to the difference of ecosystem service value and land ecological security coordination degree in Zunyi city.
