resumen

In order to study the temporal and spatial evolution of inner lakes in Dongting Lake area, this paper uses remote sensing interpretation, data statistical analysis and historical comparison methods based on 10 periods of historical topographic maps and aerospace remote sensing data since 1930s. It analyze the spatial distribution and temporal change of inner lakes in Dongting Lake area since the middle of the Republic of China. The accuracy test is carried out by using the current land using database in 2018, with the accuracy reaching 98.62%. The results show that the number and area of inner lakes in Dongting Lake area have increased from 640 and 994.30 km2 in 1938 to 1057 and 1578.33km2 in 2018. The change process did not show a continuous increasing trend, but experienced an increase, decrease, and increase. The three phases of time series change show undulating characteristics. From the middle period of the Republic of China(1930) to the early days of the founding of the People’s Republic of China(1958), the number and area of the inner lakes showed a rapid increase trend due to the massive reclamation of rivers and lakes. After that, from 1959 to 1978, inner lakes were reclaimed in large numbers because of the agricultural policy of “take grain as the key link”, number and area of inner lakes shrunk to the their lowest values since the middle period of the Republic of China (1930). Since the reform of the People’s Republic of China(1979), with the adjustment of agricultural structure, aquaculture and “returning farmland to lake”, the area of inner lakes has shown a significant increase. The inner lakes in the Dongting Lake area show an overall increasing trend, but the changes in inner lakes with different scales, types, and different characteristics in different regions are different. Diveded by scale, the areas of forbidden inner lakes (area ≥1 km2) and non-forbidden inner lakes (<1 km2) showed an overall trend of simultaneous increase and decrease, but the area changes of forbidden inner lakes have significant phases; divded by type, the area of the residual inner lakes is obviously larger than that of the reservoir-like inner lakes and the dumb inner lakes, and its area accounts for more than 70% of the total area of the inner lake; divided by region, the change in the area of the inner lake in the original polder area is divided into two stages: a decrease period and an increase period, the area of the inner lake in the new polder area is on the rise as a whole, and it has experienced a process from scratch.In general, reclamation of the lake is the main driving force for the formation of inner lakes. Food security and aquaculture are the main reasons for the change of inner lakes. The deposition and over cultivation of inner lakes e pose a serious threat to the ecological environment of inner lakes. The research results can provide objective data for the ecological restoration and environmental protection of Dongting Lake area.
