　　到了清代康熙年間，我國大規(guī)模地開展全國性地圖測(cè)量工作，繪制《皇輿全圖》的時(shí)候，吸取了歐洲制圖理論中考慮大地是球面的優(yōu)點(diǎn)，進(jìn)行經(jīng)緯度測(cè)量，并且采用了地圖投影方法。

　　During the reign of the Emperor Kang Xi (1662 -1722) in the Qing Dynasty, a complete geographical survey of the empire was carried out in preparing Huang Yu Quan Tu (Complete Atlas of the Imperial Domain). The European method of regarding the earth’s surface as a sphere was adopted. Latitude and longitude surveys were done and the projection method was used in drawing the map.

　　但是我國傳統(tǒng)的制圖理論，講求比例尺寸、方位和距離的準(zhǔn)確，仍然是測(cè)繪地圖所必須遵守的重要原則。

　　Nevertheless, the traditional Chinese rules of map-making – accurate proportion, correct orientation and precise distance – were closely adhered to by cartographers of those days.

　　現(xiàn)在柑橘在我國栽培種植得很廣，遍及長江流域以南十五個(gè)省區(qū)。

　　Today citrus are extensively grown in the 15 provinces and areas south of the Changjiang River Valley.

　　柑橘類果樹雖然喜溫，但是經(jīng)我國歷代勞動(dòng)人民精心培育，提高了它的越冬性，成功地培育出了抗寒品種。在栽培上又總結(jié)出了用實(shí)生樹引種馴化，提早進(jìn) 入休眠期，以及培土壅根等措施。

　　As such plants favor a warm climate, new varieties with better cold resistance have been cultivated through the efforts of generations of the Chinese people, who have also worked out such measures to domesticate foreign seedlings, move up the rest period and hill up the roots.

　　我國古代已經(jīng)知道果園的位置要選在比較避風(fēng)、避霜的地方。這樣盡管長江流域經(jīng)常遭受到周期性凍害，但是柑橘種植業(yè)還是不斷得到發(fā)展。

　　Since ancient times people have known that the plants should be located in areas free from wind and frost. But today with those measures, citrus growth keeps increasing in those places despite periodic frosts.
