| Oasis is the main place of the arid area of human activity and the obvious areasdisturbed by human activities, in Keriya Oasis the main Keriya river segment in thedomain, Xinjiang arid region has the typical characteristics of the effects of humanactivities Basin, Xinjiang, are chosen Keriya County as the study area, analyzed thechanges in the last20years of human factors in time and space; correlation analysis,time series and other research methods, and to determine the temporal and spatialvariation characteristics of the human factor, factor analysis,analysis of the impact onlandscape pattern and scope in order to achieve the harmonious coexistence of humandevelopment and good habitat. The main conclusions of this paper are as follows:(1) Before the humanities factor index screening, establish the principles of indexscreening, and screening population, urbanization rate, gross domestic product (GDP),the three major industries, arable land, effective irrigation area, animal husbandry,fishery total output, food production, the meat product and year-end livestock numberchange situation in Keriya County, production (pigs, cattle, sheep meat and highwaymileage, and on the basis of the formation of the human factor analysis system, andfocus.(2) In the humanities factor extraction and processing, text factor statistics:1) thepopulation/population density (people);2) the urbanization rate (urban/population)(%);3) the gross national product (GDP);4) gross national product (GNP) per capita;5) agriculture, forestry, animal husbandry and fishery output value;6)(thousandhectares) of farmland area;(thousands of hectares of7));8) effective irrigated area(thousand hectares);9) food production (t);10) at the end of livestock (ten thousand);11) the total meat (t); Spatial expression can be used for only seven indicators:1) thepopulation density (people/km2);2) the urbanization rate (%) and urban residentialareas;3) gross domestic product (GDP) and per capita GDP;4) food production;5) at the end of livestock (ten thousand) and total meat (t);6) border oasis;7) roaddistribution; And more humanistic factors of space needs to follow the five rules(3) In time series, the annual average growth rate of1.66%, higher than thewhole level of Xinjiang and even the whole country; The county urbanization ratefrom25%in1990rose to27%in2010, the growth is very slow. Keriya county GDPand three industrial output remain almost the same, the sum of per capita GDP in twodecades has increased by seven times; One cover from area, planting area ofcultivated land area> effective irrigated area, cultivated land area increased by28%in the two decades, planting area increased by16.6%, effective irrigation areaincreased by29%; animal husbandry production, total meat in20years growth isnearly three times, and the correlation coefficient of0.956, in per capita level, from2.9in1990head growth in2010to3.5per person.(4) In terms of the spatial humanities factor space difference analysis, by meansof different topography, divided into three categories: hilly plains, mountain ranges,desert. From various spatial humanities factor, human activity is the main area is hillyplains, the county-wide focus here more than90%of the logistics and energy flow,G315road runs through the east, kerryya river the river here is mainly used foragricultural irrigation, larger influence on surrounding natural ecological environment.And located in the southern town of village held and desert hinterland of Daliyobo inaccordance with the village due to the geographical environment condition such asrestriction and restriction, human activities radius is small, small to surroundingenvironment pressure also. Using factor analysis to agriculture, forestry, animalhusbandry and fishery output value of animal numbers at the end of the total meatproduction; GDP, per capita GDP; urbanization, food production, population densityand other personal factors were the development of agriculture, forestry, animalhusbandry and the level of economic consumption level, oasis cover level andpopulation load level four common factors reflect. (5) Based on based on land use change of landscape pattern dynamic analysis,adopts the three periods of TM remote sensing images in the study area for visualinterpretation and classification analysis, according to the research area of thelandscape pattern characteristics and the actual need of land cover/land use types canbe divided into8types, namely, cultivated land, forest land, grassland, water,residents use, saline-alkali land, wetland, and unused land, and to analyze thedirection and degree of the area of transfer.(6) Driven analysis process of the human factor change on natural ecosystems,focusing on population growth, arable land, food production and its per capita GDP,breeding stock in the case of their growth, expand Analysis: population growth andand economic consumption levels will drive food production increase the pressureapplied to natural ecosystems more strength, the amount of livestock growth willinevitably produce the primary productivity of forests, grasslands and increase incultivated land per capita GDP. Therefore, based on the analysis of humanity factorsimpact on the natural ecological system, priority population change, then comparedifferent humanities factor index per capita is, to separate the effects of factors onhabitat range and intensity, basically in double scales of space and time to clarify thehumanities factor the influence degree of the natural ecological system, in order totake reasonable measures to control the population, regional sustainable development.Conclusions show that through the analysis of the cultural factors of KeriyaCounty20years temporal variation characteristics of comparative analysis, thedirection and trend of the change of the human factor is obtained, reference basis wasprovided for realizing the artificial regulation and control, as well as for similarenvironment research method provides a feasible reference and support. |
