摘要

为了对自1999年起辽宁省沈阳市康平县实施的生态系统恢复工程的成效进行评估

利用多期Landsat影像解译了康平地区陆表生态系统时空分布特征; 利用气候要素回归分析、生态系统转移矩阵以及生态系统综合人类扰动指数等研究方法

对康平地区自1984年以来的陆表生态系统格局进行了研究

特别是对生态系统恢复工程实施20年来的生态系统时空变化规律进行了探索

并分析了其演变的驱动力机制。结果表明: (1)1999—2020年康平地区的生态系统格局发生显著变化

主要表现为沙地面积占比减少35.391%

耕地面积占比减少6.240%

林地面积大幅增加。(2)通过对气候要素回归分析得出

研究时间段内康平地区气候整体转湿

并且在生态系统恢复工程实施后尤为显著

适合陆表植被生长和恢复。研究最终得出

康平地区生态系统格局演变的主要驱动力为该地区自上世纪末实施的一系列生态系统恢复工程

辅助驱动力为该地区年起沙风天数减少和气候转湿的结论。

Abstract

In order to evaluate the effectiveness of the ecosystem restoration project implemented in Kangping County

Shenyang City

Liaoning Province

since 1999

the temporal and spatial distribution characteristics of the land surface ecosystem in Kangping area were interpreted by using multi-period landsat images. The pattern of the land surface ecosystem in Kangping area since 1984 were studied by using the research methods such as the regression analysis of climate elements

the ecosystem transfer matrix and the comprehensive human disturbance index of the ecosystem. In particular

the temporal and spatial changes of the ecosystem in the past 20 years since the implementation of the ecosystem restoration project were explored and the driving force mechanism of its evolution was analyzed. The results showed that: (1) During 1999—2020

the ecological system pattern of Kangping area changed significantly

which was mainly reflected in reduction of the proportion of sandy land by 35.391%

reduction of the proportion of cultivated land by 6.240%

and a substantial increase in the area of forest land. (2) Through regression analysis of climatic elements

we found that the overall climate in Kangping area became wet during the study period

especially after the implementation of the ecosystem restoration project

which was suitable for the growth and restoration of land surface vegetation. Finally

it was concluded that the main driving force for the evolution of the ecological system pattern of Kangping area was a series of ecosystem restoration projects implemented in the region since the end of the last century

and the auxiliary driving force was the decrease of the days of the sand-driving wind per year the climate humidification in the region.
