【摘要】：近年來(lái),隨著神木縣煤炭產(chǎn)業(yè)的飛速發(fā)展,縣域經(jīng)濟(jì)呈跨越式增長(zhǎng),帶動(dòng)了神木縣各項(xiàng)事業(yè)的蓬勃發(fā)展。在此背景下,神木縣土地資源發(fā)生了較大變化,建設(shè)用地供不應(yīng)求,廢棄工礦用地處于閑置狀態(tài),耕地資源總量大幅下降等等;盲目開(kāi)發(fā)土地資源給原本脆弱的生態(tài)環(huán)境帶來(lái)的負(fù)面影響也是顯而易見(jiàn)的。所以,要緩解神木縣用地矛盾、有效增加耕地面積、提高糧食產(chǎn)量、改善生態(tài)環(huán)境,必須對(duì)神木縣的耕地后備資源進(jìn)行分析評(píng)價(jià)。關(guān)于耕地后備資源的開(kāi)發(fā)利用,既要保證數(shù)量,更要保證質(zhì)量,還要合理安排。因此在摸清耕地后備資源總量的基礎(chǔ)上,有必要對(duì)耕地后備資源開(kāi)發(fā)時(shí)序進(jìn)行專(zhuān)項(xiàng)研究,這對(duì)于后期科學(xué)、有序的組織耕地后備資源開(kāi)發(fā)利用工作、調(diào)整和優(yōu)化土地利用結(jié)構(gòu)、制定合理的土地整理規(guī)劃具有重要的現(xiàn)實(shí)意義。本文主要研究?jī)?nèi)容和成果有以下兩個(gè)方面:(1)采用“限制性因子”評(píng)價(jià)法對(duì)神木縣耕地后備資源的宜耕性進(jìn)行分析評(píng)價(jià),結(jié)果表明神木縣宜耕后備資源區(qū)域分布差異大。位于縣境北部沙漠草灘區(qū)的宜耕后備資源潛力占全縣總面積的78.17%;位于縣境中部丘陵溝壑區(qū)的宜耕后備資源潛力占全縣總面積的7.25%;位于縣境東南部土石山區(qū)的宜耕后備資源潛力面積占全縣總面積的14.58%。(2)從關(guān)乎耕地后備資源開(kāi)發(fā)的自然優(yōu)勢(shì)度、經(jīng)濟(jì)支持度、社會(huì)接受度三大方面構(gòu)建耕地后備資源開(kāi)發(fā)時(shí)序評(píng)價(jià)指標(biāo)體系,研究神木縣耕地后備資源開(kāi)發(fā)時(shí)序。根據(jù)評(píng)價(jià)分值的大小確定耕地后備資源的開(kāi)發(fā)時(shí)序,得分越大越接近1,開(kāi)發(fā)時(shí)序越靠前,得分越小越接近0,開(kāi)發(fā)時(shí)序越推后。經(jīng)評(píng)價(jià)后,確定神木縣耕地后備資源開(kāi)發(fā)主要受自然優(yōu)勢(shì)度的影響,受經(jīng)濟(jì)支持度和社會(huì)接受度的影響相對(duì)較小。
[Abstract]:In recent years, with the rapid development of the coal industry in Shenmu county, county economy leaping growth, driven by booming Shenmu undertakings. Under this background, changes of land resources in Shenmu county, construction land supply, abandoned industrial land in idle state, the total amount of cultivated land resources declined sharply negative and so on; influence of the blind development of land resources brought to the fragile ecological environment is obviously. So, in order to alleviate the Shenmu land conflicts, effectively increase the cultivated area, increase food production, improve the ecological environment, to analysis and evaluation of reserve resources of cultivated land in Shenmu county. Development and utilization of arable land reserve resources, both to ensure the number, but also to ensure the quality, but also reasonable arrangements. So based on the total amount of arable land reserve resources to find out, it is necessary to reserve land resource development special time This study, for the latter part of science, development and utilization of cultivated land resources organization work orderly, adjust and optimize the structure of land use, reasonable land consolidation planning has important practical significance. In this paper, the main research contents and results are the following two aspects: (1) suitability by "limiting factor" evaluation method of Shenmu county land reserve resources are evaluated. Results show that the difference of regional distribution of Shenmu arable reserve resources. County is located in the northern desert marsh area of arable reserve resources potential of total area of the county accounted for 78.17%; county is located in the territory of the Middle Hilly Region of arable reserve resources potential accounted for 7.25% of the total area of the county is located in the southeast; Department of mountainous area of arable area reserve resources potential of the county's total area of 14.58%. (2) from the related land reserve resources development natural advantage, economic support, social acceptance To construct the evaluation index system of cultivated land reserve resources development series three aspects of Shenmu county land reserve resources development. According to the temporal development of sequential evaluation score to determine the size of arable land reserve resources, the bigger the score is close to 1, the development of sequential front, the smaller score closer to 0, the more push. The development of sequential evaluation. To determine the effect of the development of reserve resources of cultivated land in Shenmu county is mainly affected by the natural advantage degree, economic support and social acceptance of a relatively small impact.
