City air is in a sorry state. It is dirty and hot. A possible answer to the twin problems of pollution and heat is trees. To cool an area effectively， though， trees must be planted in quantity. Unfortunately， not all cities are blessed with parks or even ornamental street trees in sufficient numbers.

城市的空氣處于亞環(huán)境狀態(tài)，又臟又熱。對于空氣污染和高溫這兩個緊密相關(guān)的問題，種樹可能是一種解決方法。不過，為了能有效地給一個地區(qū)降溫，必須大量種植樹木。不幸的是，并不是所有的城市都那么幸運(yùn)，能夠打造公園，有些城市甚至都沒有足夠數(shù)量的裝飾性行道樹。

One group of botanists believe they have at least a partial solution to this lack of urban vegetation. It is to plant miniature simulacra of natural forests， ecologically engineered for rapid growth. Over the course of a career that began in the 1950s， their leader， Miyawaki Akira， a plant ecologist， has developed a way to do this starting with even the most unpromising derelict areas.

一個植物學(xué)家小組認(rèn)為，對于城市缺乏植被的問題，他們找到了解決這一問題的部分辦法。那就是模擬天然森林，種植一片微型森林；經(jīng)過生態(tài)工程改造，讓人工種植的微型森林可以快速生長。這個植物學(xué)家小組的組長是植物生態(tài)學(xué)家宮協(xié)昭，他的職業(yè)生涯從20世紀(jì)50年代延續(xù)至今。其間，他發(fā)明了一種可以在城市種植微型森林的方法，即使是在最沒有希望的廢棄地區(qū)也可以成功種植。

Dr Miyawaki’s insight was to deconstruct and rebuild the process of ecological succession. The Miyawaki method skips some of the early phases and jumps directly to planting the kinds of species found in a mature wood.

宮協(xié)博士的見解是：通過解構(gòu)和重建生態(tài)演替過程來種植微型森林?！皩m協(xié)造林法”跳過了某些早期階段，直接跳到種植那些能夠在成林中找到的品種這一步驟。

Dr Miyawaki has supervised the planting of more than 1，500 of these miniature forests， first in Japan， then in other parts of the world. Miyawaki forests can be customized to local requirements. A popular choice is to include more fruit trees than a natural forest might support.

宮協(xié)博士指導(dǎo)了超過1500個這樣的微型森林種植項目，首先是在日本，然后發(fā)展到了世界上的其他地區(qū)。宮協(xié)森林可以根據(jù)當(dāng)?shù)氐男枨筮M(jìn)行定制。一個受歡迎的定制選擇是，在微型森林中種植果樹，其數(shù)量比天然森林中能夠生長出來的果樹更多。

What pomologists offer looks like a modern version of the 19th-century movements that brought city parks and their associated health benefits to the industrializing West. The purpose is the same as before—to introduce rus in urbe.

果樹種植專家提供的方案看起來像是19世紀(jì)某些運(yùn)動的現(xiàn)代版本，那些運(yùn)動為工業(yè)化的西方國家?guī)チ顺鞘泄珗@，以及與之相關(guān)聯(lián)的健康裨益。這個方案的目的也和以前一樣——在城市中引入鄉(xiāng)村生態(tài)。

If your goal is to better your immediate locale—and maybe to grow a few guava on the side—then Dr Miyawaki might well be your man.

如果你的目標(biāo)是改善你附近的居住環(huán)境，或者是想在旁邊種植一些番石榴，那么宮協(xié)博士很可能就是你要找的人。
