云南产茶区双江景观生态风险分析

Landscape Ecological Risk Analysis in Shuangjiang County of a Tea Producing Area in Yunnan Province

以双江1995、2005、2015年3期土地利用类型面积汇总数据为基础,从土地利用动态变化、景观生态风险评价及景观生态风险空间分布变化三方面对研究区景观生态风险分布变化进行分析研究。结果表明,在1995—2015年,双江各景观生态风险区面积变化呈现低、较低和中等生态风险区面积增加,较高生态风险区面积先增后减,高生态风险区面积逐渐减少的趋势。双江县在1995—2015年的景观生态风险区组成是由以中高风险区为主向低风险区为主过渡的,为了保障该区域景观生态环境安全,双江的森林康养旅游和少数民族茶文化旅游开发应考虑生态经济效益需求及可持续发展。

Based on the data of land use types of Shuangjiang County in 1995,2005 and 2015,the changes of landscape ecological risk in the region were studied from 3 aspects of land use dynamics,landscape ecological risk assessment and spatial distribution change of landscape ecological risk.Research showed that from 1995 to 2015,landscape ecological risk areas in Shuangjiang County generally showed an increase in the low,lower and medium ecological risk areas,higher ecological risk areas increased first and then increased,high ecological risk areas gradually decreased.The composition of the landscape ecological risk areas from 1995 to 2015 was a transition from a medium-high risk area to a low risk area.Therefore,In order to ensure the safety of the landscape ecological environment in the region,the development of forest health tourism and ethnic tea culture tourism should meet the needs of ecological and economic benefits and sustainable development.
