Jianghan Plain;lake wetlands;spatial and temporal changes
摘要：
After the cataclysm of the Yangtze River in 1998, the State Council put forward the "thirty-six-word policy" for harnessing large rivers and lakes. Jianghan Plain is one of the main areas to get harnessed according to the policy. Based on the CAS land use databases of 1995, 2000, 2005 and 2010, the spatial changes information of lakes in Jianghan Plain were captured and analyzed under the ARCGIS platform or by indexes of landscape ecology. The results show that: From 1995 to 2010, the area of lake wetlands has been grown constantly; Transitions from farmland and unused land to lake were dominant for the increase of lake area, while so were the transitions reversely; Lake wetlands were divided into two categories (lake and pond) to be analyzed according to the area of every lake wetland patch, lakes mainly increased in the area while ponds mainly increased in the number of patches. Ponds are not as curved as lakes in shape and more dispersed than lakes; Lakes became less curved and concentrated with the augment of the area of lake wetlands. The shape of pond wetlands changed little and its distribution became a little concentrated with the increasing number of pond wetlands. During the three five-year analyzed, the increase of wetlands of Jianghan Plain was notable during the period of from 2000 to 2005, though the area of wetlands increased during all the three periods.

摘要：
The land use structure changes during 2000-2005 in agricultural landscape in Jianghan Plain are described, using following indices: landscape percentage (%LAND), patch density (PD), mean patch size (MPS), total edge length (TE), mean shape index (MSI) and landscape shape index (LSI). The spatial land use data was from land use database of CAS. Through interpreting Landsat TM images of 2000 and 2005 respectively, the land use change data was extracted to describe the overall agricultural landscape structure changes during 2000-2005 by spatial analysis with Supermap platform. The results show that arable land, woodland and unused land have decreased while the grassland, water areas and construction land have increased. The noticeable changes are the decreased arable land and the increase in lakes, reservoirs and ponds. Amongst the landscape indices are the increases in MPS and MSI and the decreases in PD, TE and LSI. The indices suggest that the agricultural landscape in the study area becomes less fragmental and heterogeneous resulting from intensification of agriculture and agricultural mechanization. The study shows that the changes in the agricultural landscape pattern are caused not only by urbanization but also by the governmental policies, such as the conversion of farmland to lakes, agricultural restructuring and land development and arrangement.

摘要：
Jianghan Plain is one of the most important commodity grain-, edible oil-, and cotton-growing areas. There are 764 thousand hm<sup>2</sup> of medium-low yield fields in the area affected by waterlogged soils, which accounts for 40.6% of the area of anthrosols. We chose Sanhu Farm as a study area to research if the present land use patterns match the physical properties of anthrosols profiles. Eleven soil profiles were randomly selected and samples from respective soil horizons were taken back to the laboratory for selected physical analyses. Measurement of some physical properties of the 11 profiles such as hardness and water table were made in the field, while water content, bulk density and porosity of every soil horizon were analyzed in the laboratory. The results show that land use patterns of four profiles did not match their soil physical properties totally;the physical properties of other three profiles needed to be modified in some way to match the present land use patterns. There are low water table and poor drainage problems in some profiles. Changes to soil use patterns, improve drainage ability and application of more organic fertilizers should be prime measures to improve soil producing ability in this area.

The subsided area;ecological reconstruction;zoning utilization of land
摘要：
The subsided land of mining area is not only the land and ecological environment damage caused by the exploit of mineral resources but the very important land resource to sustainable development of the Resource-based cities. A view is put forward that the ecological reconstruction of collapsed land of the Resource-based cities should be planed based on its zones. Taken the Pingdingshan City as a case, the zoning ecological reconstruction plan of the collapsed land was made based on location theory, being accord to the urban function zones and development planning. The zoning plan will change the spontaneous agricultural reclamation to integrity of multi-use and from the single benefit of agriculture to the multi-gain of ecology and economy.
