【摘要】：歷史時(shí)期的土地利用/覆被變化(LUCC)是現(xiàn)代土地利用/覆被的先導(dǎo)和基礎(chǔ),現(xiàn)代土地利用/覆被是歷史時(shí)期土地利用變化的延續(xù)和發(fā)展。進(jìn)行歷史時(shí)期LUCC研究有助于正確認(rèn)識(shí)歷史進(jìn)程中人地關(guān)系及人地和諧發(fā)展的內(nèi)在機(jī)理,對(duì)于人類當(dāng)前和未來的生產(chǎn)活動(dòng)與合理的土地利用方式有著重要的借鑒意義。本文通過訂正1393-1910年江西省域人口、耕地?cái)?shù)據(jù),以現(xiàn)代耕地分布格局為基礎(chǔ),將高程、坡度、距最近河流距離和人口密度等因子與耕地空間分布的關(guān)系進(jìn)行量化,建立起1km×1km歷史耕地網(wǎng)格化分配模型。將1393年、1491年、1578年、1661年、1782年和1910年的省域耕地面積數(shù)據(jù)帶入網(wǎng)格化重建模型,得到6個(gè)時(shí)間斷面的耕地空間分布格局。在此基礎(chǔ)上采用累積變化率、時(shí)空變化指數(shù)(STVI)對(duì)明清時(shí)期耕地時(shí)空變化進(jìn)行分析。結(jié)果顯示:(1)明清時(shí)期江西省耕地?cái)?shù)量較為穩(wěn)定,1393-1578年耕地面積略有下降,1661-1782年逐漸增加,1782-1910年緩慢下降,耕地面積受人口數(shù)量影響顯著;(2)從空間分布上來看,耕地主要集中分布在贛江中下游河谷平原區(qū),呈現(xiàn)環(huán)狀向外部逐漸減少的趨勢,且該區(qū)域STVI值較高,指示該區(qū)域耕地分布較為穩(wěn)定;(3)通過將1980年耕地?cái)?shù)據(jù)帶入重建模型,其結(jié)果與遙感解譯數(shù)據(jù)呈顯著正相關(guān),相關(guān)系數(shù)為0.82,這在一定程度上表明該模型能夠較好的重建歷史時(shí)期耕地空間分布,具有一定的合理性。在上述研究基礎(chǔ)上,本文還選取了歷史數(shù)據(jù)較為豐富的1820年為時(shí)間斷面,采取治所鄰近度分析、適宜性評(píng)價(jià)等方法重建江西省1820年1km×1km空間格網(wǎng)下的主要地類空間分布,并將重建后的1820年土地利用數(shù)據(jù)和1980年土地利用現(xiàn)狀數(shù)據(jù)進(jìn)行比較分析。研究結(jié)果表明:(1)重建結(jié)果通過了顯著性檢驗(yàn),表明重建結(jié)果較為合理;(2)1820年江西省耕地、城鎮(zhèn)用地、農(nóng)村居民點(diǎn)用地、水域及其他土地面積分別為29228 km2、105 km2、1648 km2、3730 km2、134227 km2,其中耕地主要分布在吉安、建昌以北的贛江中下游河谷平原區(qū),城鎮(zhèn)用地及農(nóng)村居民點(diǎn)用地分布則較為零散,主要分布于河流兩岸及河流交匯處;(3)從1820到1980年,江西省土地利用空間總體分布未發(fā)生大的改變,但受人口增長的影響,全省城鎮(zhèn)用地、農(nóng)居點(diǎn)和耕地的面積分別增加了364 km2、462 km2、16276 km2。
[Abstract]:Land use / cover change (LUCC) in historical period is the forerunner and foundation of modern land use / cover, and modern land use / cover is the continuation and development of land use change in historical period. The study of LUCC in historical period is helpful to correctly understand the inherent mechanism of the relationship between man and land and the harmonious development of man and land in the historical process. It has important reference significance for the current and future production activities and rational land use mode of human being. By revising the data of population and cultivated land in Jiangxi Province from 1393-1910, based on the distribution pattern of modern cultivated land, this paper quantifies the relationship between elevation, slope, distance from nearest river and population density and the spatial distribution of cultivated land. A grid allocation model of 1km 脳 1km historical cultivated land was established. The data of cultivated land area in 1393, 1491, 1578, 1661, 1782 and 1910 were brought into the grid reconstruction model, and the spatial distribution pattern of cultivated land with 6 time sections was obtained. On this basis, the temporal and spatial changes of cultivated land during the Ming and Qing dynasties were analyzed by using the cumulative change rate and spatiotemporal change index (STVI). The results showed that: (1) the cultivated land quantity in Jiangxi Province was stable in Ming and Qing dynasties, the cultivated land area decreased slightly in 1393-1578, increased gradually in 1661-1782, and decreased slowly in 1782-1910, and the cultivated land area was significantly affected by the population; (2) from the spatial distribution point of view, the cultivated land is mainly concentrated in the plain area of the middle and lower reaches of Ganjiang River, showing the trend of decreasing gradually to the outside, and the STVI value of the region is higher, indicating that the distribution of cultivated land in this area is relatively stable; (3) by introducing the 1980 cultivated land data into the reconstruction model, the results are positively correlated with the remote sensing interpretation data, and the correlation coefficient is 0.82, which indicates to some extent that the model can reconstruct the spatial distribution of cultivated land in the historical period of reconstruction. It has certain rationality. On the basis of the above research, this paper also selects 1820 years, which is rich in historical data, as time section, and reconstructs the spatial distribution of main ground classes under the grid of 1km 脳 1km in Jiangxi Province in 1820 by means of proximity analysis and suitability evaluation. The land use data of 1820 and 1980 were compared and analyzed. The results show that: (1) the results of reconstruction have passed the significance test, which shows that the reconstruction results are reasonable; (2) in 1820, the cultivated land, urban land, rural residential land, water area and other land area of Jiangxi Province were 29228 km2105 km2,1648 km2,3730 km2,134227 km2, respectively. The cultivated land was mainly distributed in the plain area of the middle and lower Ganjiang River valley north of Jianchang. The distribution of urban land and rural residential land is scattered, mainly in the river banks and river intersections. (3) from 1820 to 1980, the overall spatial distribution of land use in Jiangxi Province did not change significantly, but the area of urban land, agricultural settlements and cultivated land increased by 364 km2462 km2,16276 km2., respectively, due to the effect of population growth.
