The Segmentation Research Of The Major Function In Ningxia Limited Development Ecological Region Based On The Landscape Classification

Limited development zone is one of the basic types of the major functions of the district. At the same times, in a large proportion of the national level and provincial levels of the major function area, it is the most need of the coordinated development and ecological protection and has the most difficult and largest problems in agriculture production. Limited zone of the district subdivision has a comprehensive assessment for ecological and agricultural, animal husbandry value in different types of limited development zone and has important theoretical significance and application value in Ecological protection, regional development.Limited development zone of Ningxia is Hui Community and the zone of ecological fragile and the region of agricultural. The contradiction between regional development and ecological protection is very prominent. Ningxia limited development zone is composed of limited development of agriculture zone and limited development of Ecological zone. The most area of the latter is the mountain area of Southern Ningxia, which is composed by8administrative units; there are Xiji County, Longde County, Jingyuan County, Tongxin County, Hongsipu area, Yanchi County, Pengyang County, Haiyuan county. The area is33641km2, accounting for50.66%of Ningxia. which is the focus of Ningxia poor and ecological conservation areas. The terrain is dominated by hills and mountains and is short of water resources.The article is based on the deep analysis of the theory about principal major function regionalization. Using the qualitative and quantitative methods for segmenting Ningxia limited the development of ecological region. According to the research, it will put forward relevant development strategy for different grades of limited the study township areas. To provide a strong guarantee and scientific basis of establishing the development direction and the policies of ecological protection for Ningxia ecological limited development Zone.The main contents of this paper include the following contents:(1) From the viewpoint of landscape pattern, it interpreted of remote sensing images of ecological limited development Zone and classified the research area of each villages and towns landscape, there are forest land, grassland, arable land, water, urban, rural residential and unused land. Choose a certain landscape index. The establishments of mathematical model, as a unit by township to calculate of regional landscape ecological risk index and Human activities suitability index. It can get the subdivision scheme I by the corresponding relationship method.(2)It is using the method of mathematical statistics from the ecological fragility, ecological importance and development potential as basic data. Applying principal component analysis and comprehensive index method to segment limited development ecological zone to get The subdivision scheme Ⅱ.(3)Combined with the subdivision scheme Ⅰ,Ⅱ, according to the corresponding relationship method and the township economic development strategy, it can obtain the detailed subdivision schemeⅢ with qualitative and quantitative methods of Ningxia ecological limited development Zone.Weak limited development zone, including17townships, respectively:Huamachi town, Dashuiken town,Huianpu town,Yuhai town, Weizhou town,Hongsipu town,Taiyangshan town,Haicheng town,Sanhe town,Zhengqi town,Jiqiang town,Gaoya town,Jiangtai town,Baiyang town,Chengguan town,Zhangcheng town,Wangwa town,Liancai town;Moderate limited development zone, including33townships, respectively:Xinglong town,Shishi town,Yuwang town,Wangtuan town,Tianlaozhuang town,Xian town,Liwang town,Qiying town,Jiatang town,Shutai town,Hongyang town,Guanzhuang town,Gancheng town,Lijun town,Jiucai town,Shidian town,Caowa town,Xinglong town,Xinying town,Xitan town,Wangmin town,Shenzi town,Malian town,Xiaohe town,Gucheng town,Xinji town,Shatang town,Shenlin town,Yanghe town,Fengling town,Wenbao town,Shanhe town,Chenjin town;Strong limited development zone consists of15villages and towns, respectively:Xiamaguan town,Dingtang town,Magaozhuang town,Dahe town,Guanqiao town,Hongyao town,Majian town,Xingping town,Shagou town,Baiya town,Chengyang town,Honghe town,Guanzhuang town,Haoshui town,Dianan town;The prohibition of the development zone including27townships, respectively:Gaoshawotown,Wanglejing town,Qingshan town,Fengjigou town,Mahuangshan town,Yashan town,Hexi town, Zhangjiayuan town,Nanchuan town,Pingfeng town,Tianping town,Zhenhu town,Piancheng town,Huoshizhai town,Fengzhuang town,Luowa town,Jiaocha town,Xiaocha town,Mengyuan town,Caomiao town,Xiangshui town,Jingyuanhe town,Liupanshan town,Xinmin town,Xingsheng town,Huanghua town,Dawan town.(4) According to the Ningxia limited development of ecological zone subdivision schemes, article provides a general description for all kinds of limited development zone’s future development strategy.
