Abstract: |
Zhumadian city is located in the south of Henan province in China, and is the Changjiang River and the Huaihe river’s basin. The west of Zhumadian city is the Funiu Mountain and Tongbai Mountain, flows The Huanghuai plain is located in the east of Zhumadian city.The whole region has 3 types of physical and geographic districts, namely mountain, plain and hill. The upstream area of Zhumadian city (32°18′ to 33°35′ N and 113°10′ to 115°12′ E) has an area of 1.50×105 km2. It includes 9 counties and one district. The 9 counties are Zhengyang county, Queshan county, Xincai county, Biyang county, Pingyu county, Runan county, Suiping county, Shangcai county and Xiping county. The population is 8.53×107 in 2009. Now, economical and ecological issues from these past decades are now urgently right in front of us. In this paper, combined with fieldwork, two Land-sat TM images (1996a and 2005a) and geography information system are
used to interpret land use and land cover changes of Zhumadian city in Henan province. The results show that the changes have taken place in land use and land cover in the region since 1996. Based on the analysis of eco environmental effects of different region, this paper offers some strategies for ecological restoration in Zhumadian city basin of Henan province. Firstly, forest in the mountainous area of region should be protected to prevent further deforestation. It is import to increase water conservation ability and to protect its ecological function. In the plain of the region, no more cropland should be exploited, agricultural structures should be adjusted to utilize the limited water resources and some industries that have high water need or high pollution outputs should be restricted or canceled. Combating desertification should be a matter for urgent attention. This indicated that the returning land for farming to forestry was an effective measure of soil and water conservation. This kind of change to land use was propitious to the alleviation of soil erosion. The environmental restoration should have a high priority on the National Government Agenda Policy.
